attack on titan final season booster box WEISS SCHWARZ and super rare cards Weiss Schwarz] Attack on Titan:

I use the first opponent-controlling card, Mindslaver, as a weathervane of sorts to measure up the rest of these powerful effects

Im putting it here tentatively on that list, but things could change

SR Super Rare Worldsea Dragon Zealantis X WATER Link 4 [ Sea SerpentLinkEffect ] ATK 2500 DEF - 1+ Effect Monsters You can only control 1 "Worldsea Dragon Zealantis"

Even just a simple monster like Luster Dragon jumps to 2700 ATK when you banish another Level 4, but banishing Red-Eyes Black Dragon gets it to 3300 ATK, and Blue-Eyes White Dragon could boost it to a whopping 3500 ATK

This could be your own creature for a pump spell, or an opposing one when you aim a removal spell at it
