Scholar of the Lost Trove + Helvault + Krark-Clan Ironworks

Scholar of the Lost Trove

Helvault

Krark-Clan Ironworks

How it works

1. Activate Helvault by paying 1 and tapping it, exiling Scholar of the Lost Trove.
2. Activate Krark-Clan Ironworks by sacrificing Helvault, adding CC.
3. Helvault leaves the battlefield, returning Scholar of the Lost Trove from exile to the battlefield.
4. Scholar of the Lost Trove enters the battlefield, casting Helvault from your graveyard without paying its mana cost.
5. Repeat.
