* 702.74. Prowl #
*
* 702.74a Prowl is a static ability that functions on the stack. "Prowl [cost]" means
* "You may pay [cost] rather than pay this spell's mana cost if a player was dealt combat
* damage this turn by a source that, at the time it dealt that damage, was under your
* control and had any of this spell's creature types." Paying a spell's prowl cost follows
* the rules for paying alternative costs in rules 601.2b and 601.2e-g
