Whenever you cast a nonlegendary creature spell with flying, you may copy it, except the copy is a 1/1 Spirit in addition to its other types. Do this only once each turn. (The copy becomes a token.)
Cast nonlegendary flying creatures to get a free 1/1 Spirit copy each turn, building a wide evasive board while doubling powerful enter-the-battlefield triggers. Flicker and reuse those bodies for value, then close with an alpha strike or an ETB-based combo.
Generates a free token every turn just by playing your normal flyers, snowballing board presence
Doubles powerful flying-creature ETB effects (Mulldrifter, Cloudblazer, etc.) for huge value
Evasive board of flyers is hard to block and pressures life totals quickly
Mono-blue gives access to the best counterspells, card draw, and protection
The copy trigger only fires once per turn, limiting explosive turns without flash/flicker enablers
Mono-blue struggles with board wipes and removal that hit your fragile token swarm
Tokens are 1/1s that die to any sweeper, so you're vulnerable to Wrath effects
Slow to close if the commander is repeatedly removed and you lack a backup wincon
Protects your key creature spells from counterspells so the copy trigger reliably resolves.
Add flash and flicker enablers (Vedalken Orrery, Conjurer's Closet, Ghostly Flicker) so you can retrigger Donal and ETB flyers more than once per turn. Lean into payoffs like Panharmonicon and anthems (Favorable Winds, Intangible Virtue) to turn the token swarm lethal, and tighten the mana base with fast lands and protection like Cavern of Souls and Heroic Intervention-style blue counters to keep your engine online against wipes.
