Grenzo, Dungeon Warden + Orcish Bowmasters + Ashnod's Altar + Barkform Harvester

Grenzo, Dungeon Warden

Orcish Bowmasters

Ashnod's Altar

Barkform Harvester

How it works

1. Activate Barkform Harvester by paying 2, putting Orcish Bowmasters on the bottom of your library from your graveyard.
2. Activate Grenzo by paying 2, putting Orcish Bowmasters into your graveyard from the bottom of your library, and then putting it onto the battlefield.
3. When Orcish Bowmasters enters the battlefield, it triggers, dealing 1 damage to any target, then creating a 0/0 Orc Army creature token and putting a +1/+1 counter on it.
4. Activate Ashnod's Altar twice by sacrificing the Army and Orcish Bowmasters, adding CCCC.
5. Repeat.
