Combined with a seven in defense, this then becomes a nearly unstoppable card

You get lots of power for no mana investment since the cards never have to hit play, plus you enable graveyard and empty hand synergies for cards like Accumulated Knowledge and Ensnaring Bridge

Obviously, this makes it a pretty good MTG card, as you dont have to spend your entire turn removing everything

and "planeswalker" spells that summon powerful allies that act similarly to other players

It has plenty of brain muscle that doesn't even allow you to buy time on walls like tokens

C Common Chaos End X SPELL You can only activate this card if 7 or more of your cards are currently removed from play
