Random Generator gave me Power Sink and Fervor. Oh that feels much better after yesterday's mashup which just didn't feel right no matter what I did. I can see that the Gargoyle is going to move to the workbench. I like this one, though.

Hmmm. Like the idea; but don't see a good way to word it. Timing is confusing; I think.

It's relatively clear that if a creature loses haste in response to your tapping it to activate an ability; it's too late, it's already activated (though that'll cause upset already) - but can you even respond to declaring attackers?

I guess the usual use is going to be "That hits the table, so I dehaste it" which kinda works...

Dunno. I like the idea (it's all hasty, unless you pay for it not to be) but I don't see a nice clean implementation - maybe make the whole thing "When a creature ETBs it gains haste unless an opponent pays "? Restricts when they can pay, I guess? It's all yucky timing templatey stuff.

Actually, yeah, Vitenka, I like your suggestion. I don't think there's really any timing issues with the previous version which weren't the same timing issues that tapping a creature before attacking didn't have.... but this way does seem much cleaner.
