what pack do you buy to get polymerization

use the Glitch!

wat glitch?

you can get it in the "first fusion" booster pack in the store.(super rare)

Bet u the newbie means the code machine as a mean to get it but holy this this is just stupid coz the card can be easily found in the "first fusion" pack, i though prefer the field card that allows u to fusion summon withouth polimerization, mainly if u depend on it alot, dont use it against Yaden Yuki though, he will spam u with fusions
