Rakdos Joins Up + Opalescence + Clone

Rakdos Joins Up

Opalescence

Clone

How it works

1. Cast Clone by paying its mana cost. Choose to have it enter the battlefield as a copy of Rakdos Joins Up.
2. Put Clone into your graveyard due to the legend rule.
3. Clone's first ability and second ability trigger, along with Rakdos Joins Up's second ability.
4. Resolve Clone's second trigger and Rakdos Joins Up's trigger, dealing damage to target opponent.
5. Resolve Clone's first trigger, returning it from your graveyard to the battlefield with two +1/+1 counters on it as a copy of Rakdos Joins Up.
6. Repeat from step 2.

This loop hinges on turning your enchantments into creatures with Opalescence, allowing Clone to enter the battlefield as a copy of Rakdos Joins Up. Because legendary enchantments are subject to the legend rule, the newly entered copy immediately dies, but its dying trigger lets it resurrect itself from the graveyard while Rakdos Joins Up's own triggers (and the clone's copied triggers) fire off to incinerate your opponent. Every iteration loops the original Rakdos Joins Up and the shapeshifting copy in a perpetual cycle of death and rebirth, endlessly pinging down life totals.
