How it works
Activate Bösium Strip by paying 3 and tapping it, allowing you to cast instants and sorceries from the top of your graveyard this turn.
Cast Hanabi Blast either from your hand or from the top of your graveyard by paying 1, targeting Crystalline Crawler.
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.
Activate Crystalline Crawler's first ability three times by removing three +1/+1 counters from it, adding 1.
Repeat from step 2.
Once you have infinite colored mana, you may instead target any other creature and/or player with Hanabi Blast.
This clever loop turns Hanabi Blast's self-returning property into an engine by redirecting its damage through Vigor, whose replacement effect transforms that prevented damage into a surge of +1/+1 counters on Crystalline Crawler. Because Doubling Season is on the board, those counters are doubled as they are placed, ensuring Crystalline Crawler accrues more than enough resources to fund the mana requirements of recasting the spell. Bösium Strip acts as a crucial backup enabler, allowing you to kick off or sustain the sequence using instants and sorceries straight from the top of your graveyard when needed.
