Kalang Tsu, the Exemplar

Eminence — At the beginning of your upkeep, if
Kalang Tsu is in the command zone or on the battlefield, you may pay {1}{r/w}. If you do, until
your next turn, the first two creature tokens you
create have base power equal to Kalang Tsu's
power.
Nontoken creatures you control with power less
than Kalang Tsu's power have myriad.
