Oobleck, Excitable Professor

At the beginning of your upkeep, you may pay
{u}{r}. If you do, until end of turn you may cast
Huntsman spells from your hand as though they
had dash, where the dash cost is equal to that
spell's converted mana cost.
Whenever a creature you control deals combat
damage to a player, you may draw a card.
"It's Doctor Oobleck. I didn't earn the PhD for fun,
thank you very much!"
