Leonardo, Worldly Warrior

This card has received an update to its Oracle text. Specifically, its first ability is now affinity for creatures, as written above.

To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Leonardo's first ability). The mana value of the spell remains unchanged, no matter what the total cost to cast it was.
