Mosswort Needle
Land (Rare)

At the beginning of your end step, if you didn't cast any spells this turn, Mosswort Needle deals 1 damage to you.

Tap: Add R or G to your mana pool.

1R: Mosswort Needle becomes a 1/1 red and green Beast creature with first strike until end of turn. It's still a land.
