collector booster box dominaria united Magic: The Gathering - JAPANESE - B 5 Uncommon Magic Dominaria United Single Collector

banish the first target, and if you do, destroy the second target

But, if you want to make use of the second ability (which the card is bad in constructed if you dont), you need to include a decent number of 1-cost Sage effects

The level decrease throws off math for summoning XYZ and Synchro monsters, thus making the opponent struggle to get their combos started, which allows Predaplant Dragostapelia to control a match

Until the end of this turn, the ATK of that monster increases by 800 when it battles an opponent's monster, and it can attack all monsters on the opponent's field once, and you cannot Special Summon monsters

Illuminor Szeras brings this effect with some new flexibility

you cannot Special Summon monsters from the Extra Deck for the rest of this turn, except Machine-Type Synchro Monsters, also, destroy that card, and if you do, Special Summon 1 "Crystron" Tuner from your Deck
