Penguin 2025 Yugioh Banlist. You can only have 1 copy maximum of a “limited” card in your main. This deck is made for the 2025.04 tcg banlist.
Note that some cards which were printed during this time are nonetheless not legal for play, like some hidden arsenal cards. The hits on this banlist is clearly an attempt to make battle phase effects/cards relevant again (tenpai incoming) and force decks to actually have a win condition/real end board instead of just generic boss monsters.
