Gaia New Support

This Deck is like Crusadia so of course it goes second to OTK. We are using Forbidden Droplets to negate your opponent's monsters' effect and to halve their ATK to start building up the OTK. We have Lightning Storm if we don't open Forbidden Droplets or if we have backrow to destroy. Red Reboot for traps. Nibiru, Ash Blossom, and Infinite Impermanence to disrupt your opponent. This deck doesn't need that much engine cards just like Salamangreat so you can play a lot more handtraps and disruptions for going second.

Your main starter is Gaia the Magical Knight since it gets you to Curse of Dragon, the Cursed Dragon which gets you Spiral Fusion which gets you Gaia the Magical Knight of Dragons (an abomination of a localization if you ask me). That is then the full OTK. Spiral Fusion gives your Gaia fusion 2600 more ATK and another attack. Gaia the Magical Knight of Dragons then gains 2600 more ATK when it destroys a monster by battle. You can also have it lose 2600 ATK to target 1 card and destroy it. Artillery Catapult Turtle gets to to Gaia the Magical Knight or Curse of Dragon, the Cursed Dragon from your deck.

Field spells include Gateway to Chaos and Charging Gaia to search Gaia cards and Charging Gaia also gives you battle phase protection. Set Rotation because there is no reason not top play it in this situation.

Spiral Spear Strike is for piercing and a sort of "win-more draw power."

Sky Galloping Gaia the Dragon Champion to search Spiral Spear Strike. Idaten and Shura because why not. Knightmare Phoenix to destroy spells and traps. Proxy F Magician to get to some Fusion Plays. Soldier of Chaos because it good.

There isn't much to explain about this deck since OTK decks relatively are very simple.
