Rakdos Joins Up + Zur, Eternal Schemer + Mercurial Pretender

Rakdos Joins Up

Zur, Eternal Schemer

Mercurial Pretender

How it works

1. Activate Zur by paying 1, causing Rakdos Joins Up to become a creature.
2. Cast Mercurial Pretender by paying its mana cost. Choose to have it enter the battlefield as a copy of Rakdos Joins Up.
3. Put Mercurial Pretender into your graveyard due to the legend rule.
4. Mercurial Pretender's first ability and second ability trigger, along with Rakdos Joins Up's second ability.
5. Resolve Mercurial Pretender's second trigger and Rakdos Joins Up's trigger, dealing damage to target opponent and causing you to gain that much life.
6. Resolve Mercurial Pretender'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.
7. Repeat from step 3.
