Is it just me or is this card very weak? In the worst scenario for the creature's owner, Whisk effectively moves the creature next to any base of its owner's choice, heals it and removes enchantments and tokens, and dims it. If the Whisk's caster is not so lucky, his opponent can use the flux gain for something better.

I think it could safely cost only 2 flux, and still not be a very good card, but playable in some decks perhaps.

Ascent is quite a poor card now, and Whisk is even worse. Is returning creatures to hand valued appropriately?

I think it is good with psions since they are better the more you keep around. It is also a disenchant essentially.
I think you would generally play this on your own guys.

I agree with jed, it's a very good card in the right deck. having creature return with a low flux cost can be brutal.

I think it's a very niche card, but that it's okay as it is now. You will almost never play this on an opponent's creature, unless they've got a big enchantment on them. I think the best case scenario is playing it on a large creature, like Barkskin Dragon, that is dying. You Whisk Away it, and replay a brand new Barkskin Dragon. You've essentially saved 4 flux.

It's nothing spectacular, but it also has a little versatility. It can get rid of enchant creatures, or it can be played as an overpriced Recall. And it's not awful against creatures that require other creatures to be sacrificed.

I wouldn't say it's a good card, but it's not trash.
