Strong, the Brutish Thespian + Agatha's Soul Cauldron + Triskelion

Strong, the Brutish Thespian

Agatha's Soul Cauldron

Triskelion

How it works

1. Activate Strong using Triskelion's ability by removing a +1/+1 counter from it, dealing 1 damage to Strong.
2. Strong triggers, putting three +1/+1 counters on it and causing you to get three rad counters.
3. Repeat an arbitrarily large number of times.
4. Activate Strong using Triskelion's ability by removing a +1/+1 counter from it, dealing 1 damage to any target.
5. Repeat step 4 as desired.

This clever loop transforms Strong, the Brutish Thespian into a self-contained artillery piece by feeding on Triskelion's sacrificed counters and activated damage-dealing ability, which are granted to Strong thanks to Agatha's Soul Cauldron. By pointing Triskelion's ability at Strong, you trigger Strong's enrage ability to continuously refuel your pool of +1/+1 counters while generating a mountain of rad counters that your text-box protection turns safely into massive lifegain. Once your stats are arbitrarily large, you simply redirect that same Triskelion ability away from Strong to blast your opponents out of the game for good.
