IJN. Ryuujou, Solomon Ranger

Flying
At the beginning of your upkeep, create two 0/1 colorless Dive Bomber artifact creature tokens
with flying. They have "Whenever this creature
attacks, it may gain +2/+0. If it does, sacrifice it at
the end of combat."
Whenever IJN. Ryuujou, Solomon Ranger
attacks, put a +1/+1 counter on all other
creatures with flying you control.
