This four-color deck is hard to discern based on the Commander cards alone, mainly because each of the cards abilities are quite different, so this may be a case of picking a preferred Commander and making some upgrades/changes to build better around that card
Main Deck 41 Arcana Triumph Joker X LIGHT Level 10 [ Warrior / Effect ] ATK -1 DEF 2500 If this card is in your hand or GY: You can send 1 "Queen's Knight", "King's Knight", and "Jack's Knight" from your hand and/or face-up Monster Zone to the GY
Nezahal, Primal Tide As a 7-mana commander, Nezahal, Primal Tide probably needs some fast mana like Sol Ring or Mana Vault to be properly built around
If you open, by chance, a Rare version of that card pack, the chance of seeing the card in any slot is increased to 5%
you cannot Special Summon monsters from the Extra Deck for the rest of this turn, except Amazoness monsters, also return the targeted card to the hand, and if you do, Special Summon this card
