Rizzo, Trick Rider

Haste
Rizzo enters the battlefield mounted to a 2/2 red Lizard Mount creature token with "Rider gets
+1/+1" and Mount {2}. After your opponents
declare blockers, you may have Rizzo dismount.
If you do, remove its mount from combat. Rizzo
gains indestructible until end of turn and deals
damage as if it weren't being blocked.
