Sumo-Patch Kids

Each time you cast a creature spell with power
greater than 4, create a 0/0 Sumo wrestler token.
Each time a sumo enters the battlefield the sumo
gets a +1/+1 counter for each other sumo on the
battlefield. All other creatures are sumo's in
addition to their other types.
"As the golden sun rises over the sunflower fields,
the mighty sumo wrestler emerges, ready to face
any challenge with unmatched prowess and a
serene spirit."
