Whenever you cast a Myr spell, create a 1/1 colorless Myr artifact creature token.
At the beginning of combat on your turn, untap each Myr you control.
,
: Put three +1/+1 counters on each Myr you control. Activate only during your turn.
Flood the board with Myr tokens and ramp via Myr creatures, then untap them all each combat to either swing for lethal or generate huge mana. Urtet's 5-color activated ability turns every Myr into a serious threat with +3/+3 each, while untapping mana Myr enables explosive turns and combo lines.
Add fast mana and fixing (Mana Crypt, Chrome Mox, Jeweled Lotus, dual lands, Birds of Paradise) to reliably hit WUBRG early. Lean into combo with Intruder Alarm, Training Grounds, and infinite-mana payoffs like Walking Ballista or Blue Sun's Zenith, and include protection (Heroic Intervention, Teferi's Protection, Swiftfoot Boots) to shield your commander-dependent board. Replace weak vanilla Myr with mana producers and tutors (Demonic Tutor, Fabricate) to find your engine pieces faster.
