This loop turns the recursion of Squee, the Immortal into an unstoppable engine for infinite colorless mana and sacrifice triggers, heavily supercharged by a cascade of static and triggered abilities. You begin by feeding Squee to Ashnod's Altar to generate raw mana, which allows you to recast the goblin directly from your graveyard thanks to its own native permission. Every time that spell is cast from outside your hand, The Thirteenth Doctor's Paradox ability triggers to drop counters onto Crystalline Crawler, whose mana-yielding ability lets you filter your resources while Hardened Scales steps in to multiply those incoming counters for maximum efficiency. While Team TARDIS isn't needed to win on the spot, it happily untaps your scaled-up forces during your end step if you prefer a more patient approach.
