How it works
Cast Ancestral Statue by paying 4.
Alela triggers, creating a 1/1 Faerie creature token.
When the Faerie enters the battlefield, Cathars' Crusade triggers twice, putting two +1/+1 counters on each creature you control.
When Ancestral Statue enters the battlefield, it and Cathars' Crusade trigger twice.
Resolve the Ancestral Statue triggers, returning it and the Faerie from the battlefield to your hand.
Resolve the Cathars' Crusade triggers, putting two +1/+1 counters on each creature you control.
Activate Crystalline Crawler's first ability four times by removing four +1/+1 counters from it, adding 4.
Repeat.
This clever loop uses Ancestral Statue as a perpetual motion machine, repeatedly casting it for four mana while using its own entrance trigger to bounce itself right back to your hand. Alela, Artful Provocateur turns each of those casts into a fresh Faerie token, which in turn fuels Cathars' Crusade to permanently swell your board with an avalanche of +1/+1 counters. Virtue of Knowledge doubles up all those crucial entrance triggers, while Crystalline Crawler acts as the mana engine, sacrificing the counters it accumulates to pay for the statue's casting cost over and over again.
