Forum:Deck Guide/Decks and Loops

TOneBy BobaFett2

In Yugioh, loops are rare and often powerful. At times, a loop may do nothing, but then a new card arrives which makes the loop overpowered. Usually, those loops have cards from them Semi-Limited, Limited, or Banned. Loops have even been used in the anime, although they were often incorrect (the loop that Yugi used to defeat Strings). Some loops can go on forever, winning you the game or simply stalling for time (the "Flint Lock" and "Butterfly Dagger - Elma" loops) whereas some loops end up running out of cards (the Quillbolt"-"Plaguespreader"-"Imperial Iron Wall" loop without "Card of Safe Return" or the "Trishula" OTK Loop where your deck size limits the number of times you can use it).

When constructing a loop-based deck, you should make sure that you know exactly how each card in the loop will interact-often, a card may not actually be usable in the loop even though it may seem so at first glance. You should also make sure that the loop can't "break" itself at random times (The "Gusto" "Exodia" loop can if you don't have everything set up correctly) and that it can win you the game or at least creates game-winning opportunities (The "Flint Lock" loop won't necessarily make you win alone).

Some of the most powerful loops involve "Symbols of Duty" and "Premature Burial" as well as either "Mass Driver"/"Cannon Soldier"/"Toon Cannon Soldier" or "Exodia" as your end goal. The loops most commonly use the two Level 6 "Ice Barrier" Synchro Monsters, "Brionac, Dragon of the Ice Barrier" and "Dewloren, Tiger King of the Ice Barrier".

The Fish Synchro OTK Loop is a powerful loop that is started by using "Superancient Deepsea King Coelacanth". To make the loop, you'll need:
 * Superancient Deepsea King Coelacanth x3
 * Fishborg Blaster x3
 * Symbols of Duty x3
 * Any other Equip Spell Card x2
 * Power Tool Dragon x2
 * Dewloren, Tiger King of the Ice Barrier x3
 * Level Eater
 * Oyster Meister x3
 * Trishula, Dragon of the Ice Barrier x2
 * Sea Dragon Lord Gishilnodon
 * T.G. Hyper Librarian
 * Formula Synchron x3
 * Star Blast

Use "Star Blast" to reduce "Coelocanth" to Level 1. By getting out two "Oister Meister" and two "Fishborg Blaster" with "Coelocanth" you can win the game. Synchro Summon a Level 8 with "Coelocanth", it doesn't matter what. Tune "Fishborg" and "Coelocanth" for "Formula Synchron", then tune "Formula" and Oyster" for "Librarian". You'll now have drawn another card and produced a token. Tune "Fishborg" and the token for a "Formula Synchron", drawing two cards, then tune "Oyster" and "Formula" to make a "Gishilnodon". Draw another card and produce a token. Now discard a card, Special Summon "Fishborg", Synchro Summon "Dewloren", and draw a card. By now, if you don't have "Level Eater" in your Graveyard, you can't win. Use "Level Eater", "Fishborg Blaster", and "Dewloren" to Synchro Summon another "Dewloren". Repeat this, then get "Power Tool Dragon". Get a "Symbols of Duty" (or try to), and use it to bring back "Dewloren". Return "Power Tool Dragon" to your hand and Synchro Summon another one. Do the same thing until you get "Symbols of Duty". Special Summon "Formula Synchron" and "Dewloren", then return "Symbols" to your hand with "Dewloren". Synchro Summon "Power Tool Dragon" then Special Summon "Level Eater" and Synchro Summon "Trishula". Special Summon "Dewloren" and "Formula" with "Symbols" and repeat, returning "Trishula" to your hand if you need more than three.

You can also turn the "Dewloren" and "Symbols" loop into a Burn Damage OTK. Once you've Synchro Summoned three "Dewloren" you can use "Symbols of Duty", return it to your hand, tribute "Dewloren" for "Mass Driver", "Cannon Soldier", or "Toon Cannon Soldier", and repeat.
