Nemesis Sliver

Irate (Whenever this creature becomes the target of a spell or ability, untap it.)
Inspired - Whenever this card becomes untapped, you may pay {2}. If you do, create a 1/1 sliver creature token. It enters the battlefield tapped and attacking. Sacrifice it at the the beginning of your next upkeep.
Other sliver you control have Irate and Inspired.
Your Nemesis is here.
