Mario, the Plumber Prodigy

{2}{g}{r/w}: Look at the top five cards of your library. You may put a dinosaur creature card from among them onto the battlefield. Put the rest on the bottom of your library in any order.
While you control a dinosaur, Mario, the Plumber Prodigy gets +3/+3 Trample and Vigilance.
When a dinosaur you control leaves the battlefield, venture the dungeon.
