This is a heavily cEDH-influenced list that seeks to combo off with cards like Sliver Queen, Training Grounds, and Cloudshredder Sliver to create infinite mana to then blow up the entire table
Every deck should be considering these cards, as they are great supplements to Rest in Peace and Grafdiggers Cage
Youve got two one-sided board clears with Toxic Deluge, which often you can set up to clear everything with 8 toughness and lower and miss your 9/9s
Now, you can sacrifice these for one mana apiece, which is nice, but its not how you win
Bearer of the Heavens Up next is Bearer of the Heavens, which is just Child of Alara on steroids
Restart the turn, except with Do-Over in exile
