In any case, I imagined my first E4 post would be about the first card I was really proud of, but Simplified cards got me too excited
Five mana to gain control of so many creatures is an incredible deal, and while you cant use those creatures to go after their former controller, you can certainly make use of them to take out another player
It also comes in various colors to suit different personal styles and preferences
Sarevok would have to be at the helm of a kind of control deck that doesnt kill creatures, generally the way black would like to operate
Aerith, Last Ancient offers a lifegain payoff you will almost never pull off in an actual game because aside from Sephiroth, Fallen Hero or Wrecking Ball Arm there's no other way to reliably get her to 7 power and very little lifegain in the deck otherwise
both cards are insanely good in Commander, but warp 1v1 Magic a lot less
