Haro, Essence of Nature

Solidarity (This creature gets +1/+1 for each other creature you control that shares a creature type with
it.)
Whenever Haro, Essence of Nature attacks, you
may search your library for a basic land card and
put in onto the battlefield with two +1/+1
counters on it. It becomes a 0/0 Elemental
creature with haste and it enters the battlefield
tapped and attacking. It's still a land.
