Mister Gutsy + Nim Deathmantle + Krark-Clan Ironworks + Captain Kathryn Janeway

Mister Gutsy

Nim Deathmantle

Krark-Clan Ironworks

Captain Kathryn Janeway

How it works

1. Activate Krark-Clan Ironworks by sacrificing Mister Gutsy, adding CC.
2. When Mister Gutsy dies, its second ability and Nim Deathmantle trigger.
3. Resolve the Mister Gutsy trigger, creating a number of Junk tokens equal to the number of +1/+1 counters that were on it.
4. If you created a Junk token, activate Krark-Clan Ironworks by sacrificing a Junk, adding CC.
5. Resolve the Nim Deathmantle trigger, causing you to pay 4 to return Mister Gutsy from your graveyard to the battlefield, and attaching Nim Deathmantle to it.
6. When Mister Gutsy enters the battlefield, Captain Kathryn Janeway trigger, revealing the top card of your library, putting the card back on top of your library, and then putting a +1/+1 counter on Mister Gutsy
7. Repeat.
