The Cavaliers are a cycle of Elemental creatures from Core Set 2020 with a ton of useful abilities
Honestly, really interested in seeing how this game's meta will develop
[EFFECT] Choose up to 3 cards in your opponents GY and shuffle them into the Deck, if you sent a Level 8 or higher monster to the GY for this effects requirement, then, this card gains 300 ATK x [The number of cards returned by this effect] until the end of the turn
Xyz: Take 1 Tuner from your Deck with an equal or lower Level than that Xyz Monster's Rank, and add it to your hand or Special Summon it
Likely loaded with ways to keep Frodo alive, either by making him unblockable or giving him all sorts of protection, this deck will likely bring some powerful Green, White, and Black synergies to play with
