Rakdos Joins Up + Starfield of Nyx + Glasspool Mimic // Glasspool Shore

Rakdos Joins Up

Starfield of Nyx

Glasspool Mimic // Glasspool Shore

How it works

1. Cast Glasspool Mimic by paying its mana cost. Choose to have it enter the battlefield as a copy of Rakdos Joins Up.
2. Put Glasspool Mimic into your graveyard due to the legend rule.
3. Glasspool Mimic's first ability and second ability trigger, along with Rakdos Joins Up's second ability.
4. Resolve Glasspool Mimic's second trigger and Rakdos Joins Up's trigger, dealing damage to target opponent.
5. Resolve Glasspool Mimic'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 turns the legend rule into a lethal weapon by exploiting how clone effects interact with enchantments and the graveyard. With Starfield of Nyx animating your enchantments into creatures, a freshly cast Glasspool Mimic can enter the battlefield as a copy of Rakdos Joins Up. Because you already control an original Rakdos Joins Up, the legend rule immediately puts the copy into your graveyard, triggering its own entry ability to resurrect itself while simultaneously triggering both enchantments' death-dealing effects. This infinite cycle of sacrifice and resurrection automatically loops through the graveyard to burn your opponent down to zero.
