Rakdos Joins Up

Starfield of Nyx

Flesh Duplicate

How it works

1. Cast Flesh Duplicate by paying its mana cost. Choose to have it enter the battlefield as a copy of Rakdos Joins Up.
2. Put Flesh Duplicate into your graveyard due to the legend rule.
3. Flesh Duplicate's first ability and second ability trigger, along with Rakdos Joins Up's second ability.
4. Resolve Flesh Duplicate's second trigger and Rakdos Joins Up's trigger, dealing damage to target opponent.
5. Resolve Flesh Duplicate'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.
