Rakdos Joins Up + Opalescence + Naga Fleshcrafter

Rakdos Joins Up

Opalescence

Naga Fleshcrafter

How it works

1. Cast Naga Fleshcrafter by paying its mana cost. Choose to have it enter the battlefield as a copy of Rakdos Joins Up.
2. Put Naga Fleshcrafter into your graveyard due to the legend rule.
3. Naga Fleshcrafter's first ability and second ability trigger, along with Rakdos Joins Up's second ability.
4. Resolve Naga Fleshcrafter's second trigger and Rakdos Joins Up's trigger, dealing damage to target opponent.
5. Resolve Naga Fleshcrafter'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 relies on transforming enchantments into creatures so they can trigger the legend rule on themselves, creating an endless cycle of sacrifice and rebirth. With Opalescence turning your non-Aura enchantments into creatures matching their mana values, a newly cast Naga Fleshcrafter can enter the battlefield as a copy of Rakdos Joins Up. Because Rakdos Joins Up is itself a legendary enchantment now brought to life as a creature by Opalescence, the legend rule immediately forces the copy to the graveyard, which triggers Rakdos Joins Up's damage-dealing ability while simultaneously bringing the copy right back to the battlefield with extra +1/+1 counters through its own recursive entry trigger. Repeating this process lets you churn through infinite death triggers and leave your opponents buried under a mountain of direct damage.
