Silas Voldaren

Whenever another creature becomes the target of
a spell, put a -1/-1 counter on that creature and a +1/+1 counter on Silas.
When Silas becomes the target of a spell, remove all +1/+1 counters from it. Other creatures you control get +1/+0 until end of turn for each counter removed in this way.
It's easy to be the life of the party when the other guests keep dying.
