Woodland Weavemaster + Agatha's Soul Cauldron + Presence of Gond + Barrenton Medic

Woodland Weavemaster

Agatha's Soul Cauldron

Presence of Gond

Barrenton Medic

How it works

1. Activate Woodland Weavemaster using the ability granted to it by Presence of Gond by tapping it, creating a 1/1 Elf Warrior creature token.
2. When the Elf Warrior enters, Woodland Weavemaster triggers, giving it +1/+1 until end of turn.
3. Activate Woodland Weavemaster using Barrenton Medic's second ability by putting a -1/-1 counter on Woodland Weavemaster, untapping Woodland Weavemaster.
4. Repeat.

This clever loop centers on turning Woodland Weavemaster into a self-sustaining engine by loading it up with key activated abilities via Agatha's Soul Cauldron. By exiling Barrenton Medic into the Cauldron, Woodland Weavemaster gains the Medic's self-untapping ability using -1/-1 counters, while Presence of Gond grants it the ability to tap and create fresh Elf tokens. Every time an Elf token enters, Woodland Weavemaster's own trigger pumps its power, allowing its mana-producing ability to generate massive resources alongside the infinite creature tokens and enters-the-battlefield triggers.
