Drover of the Mighty gets +2/+2 as long as you control a Dinosaur.
{T}: Add one mana of any color to your mana pool.

Because damage remains marked on a creature until it's removed as the turn ends, the damage Drover of the Mighty takes during combat may become lethal if you no longer control a Dinosaur later in the turn.
