Ren, Shadowblade

First strike

When Ren deals combat damage, add {e}.

Pay {e}: Create a 4/3, black Shadow Fiend token
with ephemeral. (Creatures with ephemeral do not
enter with summoning sickness. However, they will
self-destruct at the beginning of the end step.)

Run. Fight. Cower. It matters not, the shadows have come for you.
