Ulamog's Dreadsire + Thornbite Staff + Woe Strider

Ulamog's Dreadsire

Thornbite Staff

Woe Strider

How it works

1. Activate Ulamog's Dreadsire by tapping it, creating a 10/10 Eldrazi creature tokens.
2. Activate Woe Strider by sacrificing the Eldrazi token.
3. When the Eldrazi token dies, Ulamog's Dreadsire triggers, untapping Ulamog's Dreadsire.
4. Resolve the Woe Strider ability, causing you to scry 1.
5. Repeat.

This elegant loop centers on Ulamog's Dreadsire, which conveniently gains a tap ability thanks to Thornbite Staff granting it the power to ping targets, though here we simply use its native tap ability to churn out 10/10 tokens. To keep the engine running, Woe Strider provides a sacrifice outlet that immediately bins those massive Eldrazi tokens. Each time a token perishes, Thornbite Staff's triggered ability steps in to untap Ulamog's Dreadsire, allowing you to repeat the process indefinitely while Woe Strider lets you filter your draws with infinite scry triggers.
