How it works
Give Olivia deathtouch, if needed.
Activate Olivia's first ability by paying , dealing 1 damage to a creature an opponent controls, destroying it due to Olivia's deathtouch, and putting a +1/+1 counter on Olivia.
When the creature dies, Revel in Riches' first ability triggers, creating a Treasure artifact token.
Activate the Treasure by tapping and sacrificing it, adding .
Repeat from step 2.
If you have a way to give Olivia deathtouch indefinitely, you may repeat this loop whenever a creature enters the battlefield under an opponent's control.
This ingenious loop locks down the board by combining Olivia Voldaren's targeted damage with Agatha of the Vile Cauldron's cost-reducing prowess. Because Agatha lowers the activation cost of creature abilities based on her power, she makes Olivia's ping ability cheap enough to be endlessly fueled by the Treasure tokens generated by Revel in Riches whenever those pinged creatures perish. Once Olivia is given deathtouch from an outside source, every single point of damage she deals acts as an assassination, creating a self-sustaining engine that clears away enemy creatures as fast as they can arrive.
