Rhythm of the Wild

Creature spells you control can't be countered.
Nontoken creatures you control have riot.
(They enter the battlefield with your choice of
a +1/+1 counter or haste.)

"Champions, welcome! The stars have aligned!
The festival is nigh! General Radahn, mightiest demigod of the Shattering, awaits you!
A celebration of war! The Radahn Festival!"
