In the primal origin pack, there is a new beasty card, STARDUSTON. He can be played by sending all dustons on field to grave, and gains 1000 atk for each. also he prevents opponent from activating set cards and from setting cards. Opponent also can't special summon. so basically, when he hits the field, the opponent is dead.

If you are wondering why all these crazy xyz, look at astral force.

dustons are supposed to be lockdown decks, but I don't know what else to use.

More burn, deck lockdown, ground collapse, needle worm(deck crusher), shiens spy?
