Basically the combo is -1. Play Chaos Confetti/Blacker Lotus.2. (optional) Mycosynth Lattice makes all permanents artifacts so that mirrorweave effects ALL of your opponent’s cards (not just their creatures).3. Play March of the Machines OR play Tezzeret the Seeker and use his +1 so that you can use his -5 ability after step #4 during the opponent’s turn (for Blacker Lotus you must use Tezzeret) to turn all non-creature artifacts into creatures. (Chaos Confetti/Blacker Lotus is an artifact creature that you can use mirrorweave on now)4. Mindslaver to take your opponents turn.5. During that turn, use Mirrorweave targeting your Chaos Confetti/blacker lotus.6. Rip all of your opponents cards into pieces.
if you combine this deck with a way to give your opponent infinite mana and infinite draws you can tear up their entire deck
I have to wonder whether anyone has actually done this
