Repeatable mass recursion seems really powerful. There has to be a way to easily generate with sacrifice effects, leading to an infinite combo. I don't even think it matters that it's a many-card combo, since all of those cards are already in other combos that you would run in the same deck.

Oh, I am so happy I took another look at the missile before I pressed 'Post Comment'. I was rather confused Dude, since I couldn't imagine how you were easily putting the missle back on the battlefield after you sacrificed it. Yeah. You don't sacrifice the missile.

Well, the easy way to get around Dude's complaint is to sacrifice the Missile. I think there's an argument to be made that the first ability is burying the really crazy second ability anyway. That, if you wanted to have your card do something no Magic card has done before, you should just print that, and not add a rider (destroy target creature) that makes people think they're going to read something familiar.

I don't think it's a big deal to have a card that encourages an infinite combo that costs this much, though. By the time you got to this stage in the game, you probably have the game locked anyway. Remember, in order to activate the missile the first time, you either have to have enough sacrificed creatures to get to 7, then 9, or you have to pay 7 and 9 with those creatures in your graveyard. That requires quite a bit of work... even for a synergestic deck.

And, even if I'm wrong, and the deck comes together perfectly... it loses to a dedicated creature deck with 4x Shatter in response to the activation. You'll get your creatures back, but so won't I, and you can't combo to victory.

Seems reasonable. Now you need to have Sharuum the Hegemon around, plus a way to make 7 mana from creatures, to get the infinite loop :)
