Blasting Station + Furystoke Giant + Thran Vigil

Blasting Station

Furystoke Giant

Thran Vigil

How it works

1. Activate Blasting Station by tapping it and sacrificing Furystoke Giant.
2. When Furystoke Giant dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. Thran Vigil and Blasting Station trigger.
4. Resolve the Thran Vigil trigger, putting a +1/+1 counter on Furystoke Giant.
5. Resolve the Blasting Station trigger, untapping it.
6. Resolve the Blasting Station ability from step 1.
7. Repeat.

This loop turns Furystoke Giant into an infinite ammunition engine by exploiting its own persist mechanic. Every time you sacrifice the Giant to Blasting Station, it returns to the battlefield with a -1/-1 counter, which immediately triggers Thran Vigil to cancel out the counter with a +1/+1 counter by pulling the Giant through a graveyard-leaving event. Meanwhile, the Giant entering the battlefield untaps Blasting Station, readying the artifact to repeat the cycle, pelt the opponent to death, and farm infinite triggers.
