: Put three +1/+1 counters on target artifact you control. If it isn't a creature, it becomes a 0/0 Robot creature in addition to its other types. Activate only as a sorcery.
Whenever an artifact you control is put into a graveyard from the battlefield, if it had counters on it, put those counters on up to one target artifact or creature you control.
Donatello turns your artifacts into a growing robot army: tap him each turn to animate an Equipment, mana rock, or other noncreature artifact into a 3/3 (and bigger), then attack or push counters around when those artifacts die. You build a wide, counter-laden board of artifact creatures and grind out incremental advantage in mono-blue.
Add proliferate engines (Evolution Sage, Inexorable Tide, Karn's Bastion) and counter doublers (Branching Evolution) to multiply Donatello's three-counter base. Lean into strong mono-blue staples—Cyclonic Rift, Rhystic Study, Mystic Remora, and fast mana rocks that double as animation targets—and include protection like Heroic Intervention effects (Clever Concealment) plus a poison finisher for a faster clock.
