Paragus, The Ravenous

Haste, Trample, ward {2}
When Paragus enters, create two 1/1 blue fish creature tokens.
sacrifice a fish or a crab creature: look at the top seven card of your library and you may put any number of crab of fish creatures into the battlefield this way. Paragus gains +1/+1 equal to the sacrificed creature's toughness until end of turn. This ability can only be activated once per turn.
