Keputosu

Flying
{3}{w}: Deal 5 damage to target Piscine Wyvern.
{4}{w}{w}: Put a +1/+1 counter on each Bird
Wyvern you control
Keputosu was able to somewhat fly, but wasn't able
to run like other Bird Wyverns. It could run, but it
was said Keputosu was still evolving strength
in its legs for longer distances.
