vstar japanese booster box Pokémon Universe s12a Display with the potential to uncover rare and powerful Pokemon cards to add to your collection Vstar Universe Japanese Pokemon Booster

Trap Cards can be Set during the Main Phase, and are activated automatically when their activation conditions are met (even during the same turn they were Set)

But then Im still not sure why you would want to do it

Asaka activates the effect of "Knikka", revealing a Wyrm Type monster from her hand to Yuamu to send the top three cards of her Deck to the Graveyard, then she can add a "Destructor Soldier Bokka" from her Graveyard to her hand

Collecting in this way and "getting by" with the best you can find forces you to really test your skills and try out innovative plays more so than playing some powerful tier deck imo

The set contains 100 cards

this should in no way impede your decision to purchase the game.
