Vigor + Hanabi Blast + Crystalline Crawler + Oskar, Rubbish Reclaimer + Doubling Season

Vigor

Hanabi Blast

Crystalline Crawler

Oskar, Rubbish Reclaimer

Doubling Season

How it works

1. Cast Hanabi Blast by paying 1, targeting Crystalline Crawler.
2. Resolve Hanabi Blast, putting four +1/+1 counters on Crystalline Crawler due to Vigor's first ability, and then returning Hanabi Blast to your hand and discarding a card at random.
3. Oskar triggers if the discarded card was a nonland card.
4. Holding priority, activate Crystalline Crawler;s first ability three times by removing three +1/+1 counters from it, adding 1.
5. Resolve the Oskar trigger, choosing to cast Hanabi Blast if it was the discarded card by paying 1 targeting Crystalline Crawler, or choosing not to cast the card otherwise.
6. If you did not cast Hanabi Blast using Oskar, cast it from your hand by paying 1, targeting Crystalline Crawler.
7. Repeat from step 2.
8. Once you have infinite colored mana, you may instead target any other creature and/or player with Hanabi Blast.

This dazzling loop turns self-inflicted damage into an engine of continuous growth and mana generation. By pointing Hanabi Blast at Crystalline Crawler, Vigor intercepts the incoming damage and instead transforms it into a massive influx of +1/+1 counters—a yield supercharged by Doubling Season to double your gains. You can then strip those counters away using Crystalline Crawler's mana ability to generate the exact resources needed to recast the spell. Finally, Oskar, Rubbish Reclaimer stands ready to catch Hanabi Blast as you discard it, looping the burn spell right back out of your graveyard to keep the chain reaction going indefinitely.
