Herald

The Herald, known as Declarer in the Japanese and Korean version, are all LIGHT Attribute Fairy-Type monster, and the colored Heralds(which are all secondary colors) are Level 2 and have 300 ATK and 500 DEF, while Herald of Perfection is a Level 6 Ritual monster. Each of the Herald's effects focus on negating the Effects. In order to activate the colored Herald's effects, the monsters must be sent to the Graveyard from the hand, along with another Fairy-type monster. Herald of Perfection is the a combination of all heralds effect that negate effect which activate by discarding a Fairy-type monster to the Graveyard.

Herald of Creation is not included by these monsters, since it's Japanese card name doesn't contain the declarer they all do.

It should be noted that because all of the Heralds are monsters and their effects are Spell Speed 2, they cannot negate Counter Trap Cards, which are Spell Speed 3.

Playing Style
Heralds is mainly focus on sending itself and a Fairy-type monster cards to negate an activation of an opponent spell, trap or monster effect. Herald of Perfection allows you to send only 1 Fairy-type monster negate all type of activation of all effect expect for Counter Trap Card. A combination of Archlord Kristya, Herald of Perfection and a Royal Degree can completely shut down any deck.

Weaknesses
Cards that prevent Special Summoning will also keep Herald out of play, so Vanity’s Fiend and Vanity’s Ruler can shut down the Herald Duelist’s plans. Better yet, Cursed Seal of the Forbidden Spell can shut out Ritual Summons permanently: it’s a Counter Trap that lets you discard a Spell Card to negate an opposing Spell. Then, your opponent can’t activate the same Spell Card for the rest of the Duel. If you negate Advanced Ritual Art or Dawn of the Herald once, your opponent won’t be able to play them again. Remove from play can also permanently shut down Herald of Perfection's effect.

Perfect Heralds
This variation of deck focuses on use Dawn of the Herald to tribute cards from your hand or field to the Graveyard to Ritual Summon Herald of Perfection. After you have Ritual Summoned Herald of Perfection, you can use the effect of Dawn of the Herald to return 1 monster from the Graveyard that you have tributed for the special summon to your hand or not to activate the effect so you can have exactly 4 Fairy-Type monsters in the Graveyard, allowing you to Special Summon Archlord Kristya. Archlord Kristya can prevent the opponent from special summon or synchro summon. Freya, Spirit of Victory is used to boost the DEF of Herald of Perfection and the ATK of Archlord Kristya in case the opponent have monster with 3000 ATK. Royal Decree is used to prevent the activation of Counter Traps which Herald of Perfection can't negate.
