Nature's Blessing

Oracle Text

GW, Discard a card: Put a +1/+1 counter on target creature or that creature gains banding, first strike, or trample. (This effect lasts indefinitely. Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding a player controls are blocking or being blocked by a creature, that player divides that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)
