Single Card Discussion Kukemssa Pirates

[coop]

3U- Whenever Kukemssa Pirates attacks and isn't blocked, you may gain control of target artifact defending player controls.  If you do, Kukemssa Pirates deals no combat damage this turn
2/2

I randomly came across this while on MWS, and thought it could be some good powered out by mana drain.   Its an intresting card anyways, and doing a search couldn't find any talk about it(maybe theres a reason for this) so I thought I would post it.  Is this playable at all and in what decks/matchups?

This has the same casting cost as Deep Analysis, Fact or Fiction, and Gifts Ungiven.

Why would you clutter up that chunk of your mana curve for something useless against 95% of the field when you could run a real spell instead?

Just throwing out the idea, it would probably be more of a SB card, but the ability seems pretty strong and thats why I posted it.

Aladdin > This, but Aladdin is horribly slow.

Look at it this way: Unless you get a Drain or Lotus, this won't work until turn five. Let's say you cast it turn two. On turn three it MIGHT do something. But CS will most likely have out a fattie blocker, 5/3 will have stomped you into oblivion, and any other decent artifact deck will have an answer to it.

It won't work.

It's not strong. At. All. In fact it's completely awful.

Problems with the entire concept.
1. It costs 4 mana
2. It has to attack
3. It has to not be blocked
4. You steal a artifact critter. WHOOPITY DO.

If you wanted to steal artifact critters that badly, play Steal Artifact or Control Magic. Otherwise you'd play real spells.
