Orcish Bowmasters + Agatha's Soul Cauldron + Whirlpool Warrior + Ashnod's Altar

Orcish Bowmasters

Agatha's Soul Cauldron

Whirlpool Warrior

Ashnod's Altar

How it works

1. Cast Orcish Bowmasters by paying 1.
2. When Orcish Bowmasters enters the battlefield, it triggers, creating a 0/0 Orc Army token if you do not control an Army, then putting a +1/+1 counter on an Army you control and dealing 1 damage to any target.
3. Activate the Orc Army using Whirlpool Warrior's ability by paying 1 and sacrificing it, causing each player to shuffle their hand into their library, and causing each player to draw that many cards.
4. Orcish Bowmasters triggers for each card opponents draw this way.
5. Resolve the first trigger, creating a 0/0 Orc Army token, then putting a +1/+1 counter on it and dealing 1 damage to any target.
6. Activate Ashnod's Altar by sacrificing the Orc Army, adding CC.
7. Resolve the second Orcish Bowmaster trigger, creating a 0/0 Orc Army token, then putting a +1/+1 counter on it and dealing 1 damage to any target.
8. Holding priority, repeat from step 3 an arbitrarily large number of times.
9. Resolve the first remaining Orcish Bowmasters trigger, if applicable, creating a 0/0 Orc Army token if you do not control one, then putting a +1/+1 counter on an Army you control and dealing 1 damage to any target.
10. Repeat from step 9 for each remaining trigger.

This loop turns a flurry of card draw into a devastating win by utilizing Agatha's Soul Cauldron to grant Whirlpool Warrior's activated ability to your creatures. Once Whirlpool Warrior is exiled into the Cauldron and its ability is granted to your Orc Army token, you can repeatedly force all players to shuffle their hands away and draw fresh cards. Each card your opponents draw triggers Orcish Bowmasters to deal damage and amass more Orcs, providing fresh fodder for Ashnod's Altar to generate the mana needed to keep the wheel spinning.
