deoxys booster box EX Pokémon Pack a box topper in each booster display box Pokemon Deoxys/Zeraora V Battle Deck

Defense Position: Once per turn, during your Main Phase: You can add 1 Level 4 or lower "Morphtronic" monster from your GY to your hand, then place 1 card from your hand on top of the Deck

-Mixed cards: This card can not declare an attack next turn

Other erratas the community suggests include preventing the player who dropped Maxx "C" from activating any other card effects for the rest of the turn, adding an activation condition that allows Maxx "C" to only trigger after the opponent summons from the Extra Deck first, and a condition that allows the card to resolve after the opponent Special Summons a certain number of times, similar to Nibiru, the Primal Being

But I should have known better

You can only control 1 "Xyz Change Tactics"
