Harness the Lizards

When Harness the Lizards enters the battlefield,
Dinosaurs become Vehicles with crew cost X,
where X is the number of colors of that creature.
Dinosaurs you control have "{t}: For each color
of that creature, add one mana of that color to
your mana pool."
Whenever a Dinosaur becomes tapped for mana,
put a +1/+1 counter on another target creature
and draw a card.
