Blasting Station + Thunderblust + Hardened Academic

Blasting Station

Thunderblust

Hardened Academic

How it works

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

This loop turns a deadly game of recycling into a lethal artillery strike, using Blasting Station as both the sacrificial altar and the damage dealer. When you feed Thunderblust to the Station, its persist mechanic brings it right back to the battlefield bearing a -1/-1 counter, which simultaneously triggers Blasting Station to untap and Hardened Academic to notice cards leaving your graveyard. Thanks to Hardened Academic's clever triggered ability, that departure lets you place a +1/+1 counter onto Thunderblust, instantly neutralizing its -1/-1 counter through standard Magic rules so that persist can fire again the next time it dies.
