: Choose a color. Target opponent exiles the top X cards of their library. For each card of the chosen color exiled this way, create a 1/1 blue and black Faerie Rogue creature token with flying.
Oona grinds opponents out by milling their libraries while building a swarm of flying Faerie tokens, then converts that swarm into a lethal attack or a token-based combo finish. You ramp into Oona, protect her, and dump mana into her activated ability each turn to mill targets and flood the board with evasive 1/1s.
Functions as both a token engine and a mill engine in a single card, scaling with available mana
Produces evasive flying tokens that pressure all opponents and synergize with anthems and sacrifice payoffs
Built-in mana sink that uses excess mana every turn, rewarding ramp-heavy builds
Strong in UB, with access to the best removal, counterspells, and tutors to protect the plan
Six mana and reliant on a single creature; commander removal and tax effects slow her down badly
Her ability is X-mana hungry, so without big ramp the token output is anemic
Mill can accidentally fuel opponents' graveyard strategies (reanimator, delve, flashback)
1/1 tokens die to nearly any board wipe, undoing turns of work
Color randomness means activations sometimes whiff against monochrome or off-color libraries
Premier blue board reset that protects your swarm while clearing blockers for the alpha strike.
Prioritize big mana so Oona's X-ability dominates: add Cabal Coffers/Urborg, Nykthos, Gauntlet of Power, and rituals. Layer in token doublers (Doubling Season, Anointed Procession) and protection (Swiftfoot Boots, Lightning Greaves, counterspells) to keep her online. For higher power, build toward an infinite-mana or sacrifice loop—Ashnod's Altar with a token doubler turns Oona into an instant-win mill or aristocrats engine.
