pokemon booster box crown zenith Pack [10 Cards] powerful Pokmon Pokemon Sword & Shield Crown

On paper, this logic is easy to understand

The maximum combat level is a whopping -10

Target creature gets +X/+X until end of turn, where X is the number of creatures you control

It's reminiscent of Underdark Rift, which could 'tuck' a creature based on the result of a d10 die roll, though it ran the risk of rolling a one and letting the opponent redraw their threat the following turn

Once per turn: You can return as many of your opponent's banished cards as possible to their GY, and if you do, the first battle or effect damage your opponent takes this turn becomes doubled

It utilises Synchro summoning, which allows you to populate the board with low-level monsters until you summon game-ending cards from the extra deck
