Mister Gutsy + Nim Deathmantle + Krark-Clan Ironworks + Combine Guildmage

Mister Gutsy

Nim Deathmantle

Krark-Clan Ironworks

Combine Guildmage

How it works

1. Activate Combine Guildmage's first ability by paying 1 and tapping it.
2. Activate Krark-Clan Ironworks by sacrificing Mister Gutsy, adding CC.
3. When Mister Gutsy dies, its second ability and Nim Deathmantle trigger.
4. Resolve the Mister Gutsy trigger, creating a number of Junk tokens equal to the number of +1/+1 counters that were on it.
5. If you created a Junk token, activate Krark-Clan Ironworks by sacrificing a Junk, adding CC.
6. Resolve the Nim Deathmantle trigger, causing you to pay 4 to return Mister Gutsy from your graveyard to the battlefield with a +1/+1 counter on it, and attaching Nim Deathmantle to it.
7. Repeat from step 2.
