The Blood Moon

(You may only cast a legendary sorcery if you control a legendary creature or planeswalker.)

Return up to 3 creatures with power 3 or
less from your graveyard to the battlefield with +1/+0 counter on each of them.

If you don’t have enough creatures with power
3 or less in your graveyard, create X 2/1 red Goblin Mutant creature tokens, where X is the difference between the number of creatures and 3.
