Infernity

Infernity, a portmanteau of the words "Infernal" and "Infinity", are primarily DARK monster cards with effects activated when a player has no cards in their hand. This archetype was used by Kalin Kessler in Yu-Gi-Oh! 5D's. In the dub version of Yu-Gi-Oh! 5D's, these Infernity monsters, spells and/or traps were known as Infernalty.

The first Infernity cards were released as promotional cards in Yu-Gi-Oh! 5D's Stardust Accelerator: "Infernity Archfiend", "Infernity Dwarf", and "Infernity Guardian". Infernity Destroyer was released in the Yu-Gi-Oh! 5D's Stardust Accelerator - World Championship 2009 Game Guide in Japan.

The first Infernity card released in a booster set was "Infernity Beast" in Ancient Prophecy. Two additional Infernity cards soon followed with the release of Stardust Overdrive: Infernity Necromancer and the first Infernity trap card Infernity Force.

Support for the Infernity archetype "handless" theme was expanded by 15 cards in the Shining Darkness booster set.

Playing style
As the monster Effects imply, this deck is focused on having no hand. Cards such as Reckless Greed, Offerings to the Doomed, and other cards with a effect that prevents you from drawing would be an essential to this deck. Using discarding effects, such as Dark World Lightning, Fine, and The Cheerful Coffin would also give point to the Dark Worlds, such as Goldd and Sillva. This would leave you with a very small hand.

Also, since Infernity monsters specifically rely on having no cards in your hand, cards like Full Salvo would strongly help this deck. Full Salvo can make you discard all cards in your hand in order to deal 200 life points of damage to your opponent for each card you discard to the graveyard.

Used correctly, this deck can become very powerful on its own. However, it can be made even more powerful by adding in cards from one or two different Archetypes. The first is the "Dark World" series. Most of the support tends to involve discarding cards from the hand and Special Summoning from the graveyard, and most of the monsters benefit from this. With Infernity Necromancer and the upcoming release of the support cards in The Shining Darkness, Infernity cards seem to be heading that way as well. The "Dark World" cards are known for being very fast and good at swarming, which is just what the generally slow Infernity monsters need.

The other Archetype is the currently OCG Only, Duel Terminal-exclusive, "Fabled" series. Like the Dark World set, these cards focus primarily on discarding cards in the player's hand. The key difference, however, is that the Fabled do not actually discard cards to use their own effects, but rather to decrease the number of cards the player is holding, as their monsters can use their effects only when the player's hand is low on cards, or empty altogether. For this reason, they seem to fit in better with the Infernity cards. Notable cards are Fabled Raven (a Level 2, 1300 ATK Tuner monster which lets you discard any number of cards to increase its Level by 1, and its ATK by 400, for each card. This effectively lets you empty your hand to have a high Level, high power Tuner monster) and Fabled Soulkius (a Level 6, 2200 ATK monster which lets you discard two cards to Special Summon it from the graveyard, fitting perfectly into both the themes of the Infernity cards). On top of that, the "Fabled" are all LIGHT monsters, while the Infernity cards are all DARK monsters, so even the powerful Chaos Sorcerer can be splashed into this deck, and in Traditional Format, the great and mighty duo Chaos Emperor Dragon - Envoy of the End and Black Luster Soldier - Envoy of the Beginning.

Zombie-type monsters could also be mixed into an Infernity deck. Zombies tend to work off of the grave and, in turn, could be used as main discard fodder. You'll most likely summon the monsters you discarded anyway, so discarding them to kill your hand probably won't affect you much.

As of The Shining Darkness release, the Infernity archetype has become much more Graveyard based. Both Infernity Mirage and Infernity Launcher can quickly and effectively summon your monsters from the grave. And because the most common way of emptying your hand is discarding, you'll have plenty of guys in your grave to summon. Infernity Avenger can also summon himself and possibly become one of the only Lv.5+ tuners. Because of new graveyard tactics, the Infernity have become less and less reliant of topdecking, turning this rather risky deck type into a powerful tool of decimation. One of the new, upcoming cards that really boosts this archetype is Phantom Hand. With this card, players won't have to rely entirely on discarding their hand. Players can instead, once they're finished using the cards in their hand during a turn, remove them from play and instantly gain all the effects of their Infernity monsters. Then, in the next turn, they can use their hand again, like nothing ever happened. As an added bonus, this will protect cards from discarding effects. To protect Phantom Hand, Imperial Custom can be used. Use it to also protect Depth Amulet.

Since you are going to discard cards, you could harm your opponent by using Forced Requisition.

Another Tech Choice is Hate Buster as most of the Infernity monsters are Fiend and have reasonably low attack. Hate Buster gives the deck much needed protection against your opponent's strong Monsters.

Since Infernity decks can manipulate the number of DARK monsters in their Graveyard at ease, Dark Armed Dragon is a very smart addition to clear the field if you are unable to bring out powerful Synchros immediately. (Use with caution; There are some cards that would be in your Graveyard that you wouldn't want to get rid of.)

The Infernity deck structure is now able to effectively summon several high-level Synchro Monsters every turn, providing the right cards exist on the field or in-hand. A popular choice is to Synchro Summon Trishula, Dragon of the Ice Barrier or Mist Wurm, and exploit their field-clearing abilities, while Infernity Launcher (whether in the hand or on the field) will allow the player to summon a second Trishula or Wurm via Infernity Necromancer, Infernity Archfiend, Infernity Beetle and another copy of Infernity Launcher, to clear the opponent's field, hand and graveyard of any cards blocking a direct attack.

Weaknesses
Infernities, despite their enormous potential as an Instant Synchro deck, have a number of crucial weaknesses. Of course, the foremost one is the one shared among most of today's competitive decks - Special Summon and Graveyard reliance. Cards like Royal Oppression, Macro Cosmos, Dimensional Fissure, Crevice Into the Different Dimension and any other that could lock down the main assets of the deck are the most dangerous threat, with Skill Drain placing just after them in terms of threat. Side-Deck Imperial Iron Wall to combat against the removal cards, and Twister to deal with Royal Oppression and Skill Drain. Cards like D.D. Crow and Battle Fader that can be activated in hand can give major surprise also lockdown to Infernity combo. Ultimately cards like Threatening Roar and Waboku can stop Infernity from attacking and luring for the right counter.

Also, by themselves they are a fairly weak archetype, with the most powerful non-Synchro card, Infernity Destroyer, being only 2300 ATK and without a strong enough effect. Hindering the key cards of the deck with Prohibition and the like can also disrupt their strategy dramatically, since this will leave cards in hand, stopping the effects of Infernity monsters.

Infernity monsters are also severely affected by Consecrated Light. This monster prevents the normal summoning of Dark monsters; therefore disabling Synchro-Summoning. Be careful, Dark monsters can be flip-summoned. Consecrated Light will only stall for a turn or two.

Another thing to consider when building an infernity deck is that random chance you will run into a koa'ki meiru deck. You have a high chance of losing.

And if you're looking for cards to side against infernities, Book of Eclipse shuts down any infernity OTK move.

Strengths
Currently, the most noticeable strength of an Infernity deck is its ability to Instant Synchro with ease, thanks to cards like Infernity Launcher and Infernity Necromancer, which allow for very fast Special Summons from the Graveyard. Similarly to Launcher, Infernity Mirage can Special Summons two more Infernity monsters simply by being Tributed, and it's rather easy to keep a hand empty thanks to many cards like Raigeki Break, Phoenix Wing Wind Blast, Into the Void and so on. Also, the Infernity archetype has its own specific Counter-Trap in the form of Infernity Barrier, a card that can jam almost anything by itself.

If properly used, the deck can guarantee an OTK situation with its main combo, which allows for the Synchro Summon of three Lv. 9 Synchro Monsters (Mist Wurm in the TCG, Trishula, Dragon of the Ice Barrier in the OCG), plus another Synchro Monster and an Infernity Archfiend, or two Archfiends. Otherwise, it can simply use the many ways it has to Special Summon from the Graveyard to provide material for other Synchro Summons, not necessarily having to rely on big plays.

Trivia

 * In the Japanese version of Yu-Gi-Oh! 5D's when Kalin says Infernity, you can mishear him saying Infinity.


 * In Yu-Gi-Oh! 5D's episode 54 and Yu-Gi-Oh! 5D's episode 55 the word Infernity was used instead of Infernality.


 * The more recent additions of the Infernity archetype seem to have a Western Shootout theme to them.
