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.
Five-color identity means access to every removal, ramp, and tutor in the format
Doubles as a token engine and a tribal anthem in one card
The untap-all-Myr trigger creates infinite/near-infinite mana loops with mana Myr
Myr are colorless and cheap, so the deck curves out fast and floods boards quickly
Heavily reliant on the commander; board wipes and commander hate gut the strategy
WUBRG-intensive abilities demand precise five-color mana that can stumble
Tokens are individually fragile to sweepers and edicts
Without Urtet untapping Myr, the deck loses much of its mana and combat punch
