Champions of the Party

Champions of the Party cannot block.
Whenever a legendary creature or planeswalker
enters the battlefield under your control, put a
+1/+1 counter on Champions of the Party. If a legendary creature you control would die,
regenerate it and put a -1/-1 counter on
Champions of the Party.
