The Thirteenth Doctor + Squee, the Immortal + Crystalline Crawler + Ashnod's Altar + Doubling Season
How it works
- Activate Ashnod's Altar by sacrificing Squee, adding CC.
- Cast Squee from your graveyard by paying 1.
- The Thirteenth Doctor's first ability triggers, putting two +1/+1 counters on Crystalline Crawler.
- Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding .
- Repeat.
This clever loop uses Squee, the Immortal's unique ability to be repeatedly cast straight from the graveyard, feeding Ashnod's Altar for a steady stream of colorless mana while setting off the rest of your engine. Whenever you cast Squee from outside your hand, The Thirteenth Doctor triggers to place a counter on Crystalline Crawler, whose own self-contained ability to add mana of any color helps smooth out your costs. Doubling Season acts as a powerful amplifier for this entire sequence, doubling the counters placed on Crystalline Crawler so that you easily generate a surplus of mana. Finally, Team TARDIS makes sure your augmented creatures stay ready for action by untapping them during your end step, letting all these interlocking pieces run indefinitely.
