Strength of the Herd

Target creature gets +1/+1 for each goat you control until the end of turn. If that creature is a goat then it also gains trample and cannot be blocked by walls.
Splice onto goat - {w}{g} (As you cast a goat spell, you may reveal this card from your hand and pay its splice cost. If you do, add this card's effects to that spell.)
The goats ate the flavor text.
