Ciin'Rya, Kisr'iian Monarch

Convoke.
{t}{g/u}: Gain one Calmness counter. During your
turn, you may expend a Calmness counter to give
a friendly Wolf +1/+1. Wolf creatures with
Calmness must attack if able. If a Wolf creature
with Calmness is blocked and killed, gain one
Calmness counter. If you expend three Calmness counters at once, friendly Wolf instead gains
+3/+3 and Trample.
Remain at peace, darling.
Experience serenity.
