Hi, i have always thought that Team-Up cards affect only character cards.

But some cards like :

Pack Tacitcs MXM
Target character has flight and range this turn and gets +2 ATK while defending this turn. Pack Tactics has the Physical trait in your hand, deck, and KO'd pile.

make me think. Does any card get the affiliation when you play, for example, X-Men united ? Or only character cards? (Could a plot-twist card get an affiliation?) AND What about district X?



At the start of the combat phase, choose a Mutant trait. Characters you control, as well as cards in your hand, deck, and KO'd pile are Mutants and have the chosen trait this turn.

Does it give the chosen traits to every card? (And do you lose another mutant traits while playing its effect? )

From the Official Card Refferance also know as the OCR
District X was given an errata to make it "character cards" not just "cards", so no, that doesnt work
