Menace , Sacrifice another creature or enchantment: Put a +1/+1 counter on Sawblade Skinripper.
At the beginning of your end step, if you sacrificed one or more permanents this turn, Sawblade Skinripper deals that much damage to any target.
If you haven't sacrificed any permanents during your turn by the time your end step begins, Sawblade Skinripper's last ability won't trigger at all. You won't be able to sacrifice anything during your end step in time to have the ability trigger.
