Tree of Perdition + Dollhouse of Horrors + Electropotence

Tree of Perdition

Dollhouse of Horrors

Electropotence

How it works

1. Activate Dollhouse of Horrors by paying 1, tapping it and exiling Tree of Perdition from your graveyard, creating a token copy of Tree of Perdition that is a 0/0 Construct with haste.
2. When the Tree of Perdition token enters the battlefield, Electropotence triggers.
3. Holding priority, activate the Tree of Perdition token by tapping it, swapping an opponent's life total with Tree of Perdition's toughness.
4. Resolve the Electropotence trigger, causing you to pay 2 to have the Tree of Perdition token deal damage equal to its power to the opponent whose life total was swapped.
5. The opponent loses the game due to having zero or les life.

This clever loop starts by using Dollhouse of Horrors to pluck Tree of Perdition right out of your graveyard and stamp it onto the battlefield as a 0/0 Construct token. Because the token is a 0/0, its power is zero, which would normally make Electropotence's triggered ability useless; however, you exploit the stack by tapping the token to swap your unfortunate opponent's life total with its toughness *before* Electropotence's damage trigger resolves. When the Electropotence trigger finally resolves, you pay {2}{R} to have the newly weakened life total meet its sudden end, as the token deals damage equal to its power to finish the job.
