Based on Vairë the Weaver. So - what's the broken combo?

The most ridiculous that immediately leaps to mind would be morph. Yes, I unmorph a card that isn't in play. Uh...

When I heard that interpretation of the ability, the first thing that popped to mind was Gigantomancer. Certainly not the most powerful thing, but indicative of what kind of nonsense you could pull off with it.

I was thinking I would approach the ability with this kind of wording:

> You may activate abilities of permanent cards in your hand. (Reveal the card as you activate its ability. You can't tap or sacrifice permanent cards in your hand to pay costs.)

Still, there's a lot what abilities can do so I don't know how that would function. Just something like ": ~ fights target creature." sounds problematic.

What if the ability's cost is "Return ~ to its owner's hand: ..." What happens then?

Oooh, yes; that cycle is plenty potent.

Return as a cost - we're pretending you have cast it, so sure. You can return it there. Why not?

If you cast it wouldn't it be a spell on the stack? Is what you want "cast and resolved"? That's relevant because different card types would assume different zones after resolving e. g. Geistblast.

There are precious few cards that have abilities that can be activated from the stack.

You can't unmorph it though; that's a special action, not an activated ability

Um, drat - yes, I guess it should say "as though it were on the battlefield".

Re: Unmorph. Aww, that's dumb. And stupid. The rules are clearly just wrong in that regard.

Don't shock my morphs in response!

Like... why not? That sounds like a perfectly sensible thing.
