Thrummingbird (CMM 858) is a blue Creature — Phyrexian Bird Horror from Commander Masters. It has flying and an ability that proliferates whenever it deals combat damage to a player, adding additional counters of each kind already present on chosen permanents and/or players. Its low cost and repeatable proliferate effect make it a common inclusion in counter-focused or commander decks that leverage incremental value.
