Memnarch, Primus

Whenever you cast an artifact spell, create a
1/1 Myr Assistant artifact creature token with
"Myr you control get +1/+1"
Whenever an opponent casts a spell, create a
1/1 Myr Spy artifact creature under that
opponents control with "when Myr Spy dies,
sacrifice a colored permanent you control"
In the blur between madness and duty,
Memnarch found purpose.
