>>2232343There is actually a way to prevent your opponent doing literally anything, but you're never gonna actually pull it off, you might as well Exodia FTK at that point.
And I dunno, I'm not that familiar with magic, I like yugioh though. Imperial Order is busted I believe, and no one uses royal decree because traps suck for the most part. I think nowadays most of the stopping your opponent doing stuff is via handtraps.
