Titanus Ultimasaurous

Trample, haste, vigilance, firstrike

Whenever Titanus Ultimasaurous deals combat damage to a player or creature, reveal cards from the top of your library until you reveal a dinosaur spell and put it onto the battlefield untapped, then shuffle. If the dinosaur revealed was non-legendary, create 10 6/6 green dinosaur creature tokens with trample. If it was legendary, Titanus Ultimasaurous gets +10/+10.
