Dynacharge {R}

Notes and Rules Information for Dynacharge:

• If you don’t pay the overload cost of a spell, that spell will have a single target. If you pay the overload cost, the spell won’t have any targets. (2013-04-15)
• Effects that cause you to pay more or less for a spell will cause you to pay that much more or less while casting it for its overload cost, too. (2013-04-15)
• If you are instructed to cast a spell with overload “without paying its mana cost,” you can’t choose to pay its overload cost instead. (2013-04-15)
• Because a spell with overload doesn’t target when its overload cost is paid, it may affect permanents with hexproof or with protection from the appropriate color. (2013-04-15)

• Note that if the spell with overload is dealing damage, protection from that spell’s color will still prevent that damage. (2013-04-15)
• Overload doesn’t change when you can cast the spell. (2013-04-15)
• Casting a spell with overload doesn’t change that spell’s mana cost. You just pay the overload cost instead. (2013-04-15)
• An overloaded Dynacharge affects only creatures you control at the time it resolves. Creatures you begin to control later in the turn won’t get +2/+0. (2017-03-14)
