Containment Construct

Vigor

Hanabi Blast

Crystalline Crawler

Vorinclex, Monstrous Raider

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. Containment Construct triggers, allowing you to exile the discarded card from your graveyard and cast it from exile this turn.
4. Activate Crystalline Crawler by removing three +1/+1 counters from it, adding 1.
5. If you discarded Hanabi Blast, cast it from exile by paying 1, targeting Crystalline Crawler.
6. Otherwise, cast Hanabi Blast 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.
