The result of poorly-designed interfaces: generic_activated_ability() and generic_spell() can be customized in substantially identical ways, using flags that are named substantially identically; but their flags have different values, and neither is capable of detecting when it's given the other function's flags. So for example in this case, the instruction to require and select a target turned into an activation cost of .

The same problem affects (with varying effects and severities) Arenson's Aura, Flicker, Forerunner of Slaughter, Gateway Shade, Goblin Chirurgeon, Haazda Shield Mate, Hecatomb, Nihilistic Glee, Pia and Kiran Nalaar, Quillspike, Seismic Assault, Spike Rogue, Trade Caravan, and Vedalken Mastermind. All fixed in 13e1d37.

There's bugs open for Vedalken Mastermind and Flicker; the former should be fixed by this (the bug changed a prompt-changing flag into a -1/-1 counter requirement), and I'll confirm it shortly, but the latter seems unrelated. It's certainly possible that some of the others actually were working already due to having both the wrong flag and wrong kind of flag and got the correct values by accident; they'll be broken now.
