Fhir'thani, Eclipse Bringer

Flying, riot, rampage 2 (Whenever this creature
becomes blocked, it gets +2/+2 until end of turn for
each creature blocking it beyond the first.)
When Fhir'thani, Eclipse Bringer is casted, all
your creature onto the battlefield gains and
actives riot, and every creature in your hand and library gains riot.
The eclipse is approaching... and with it, the fury of
Fhir'thani, we have no chances to win this battle
anymore.
