I had a very similar idea, just browsed through previous ideas to see if anyone else came up with it. I was thinking no player effects, only field effects. Poison and aflatoxin damage. Freeze, delay reduced. Shield counters reduced, making this powerful against an aether deck. Acceleration, malignant cell...there are probably some other fun ones I'm forgetting. I like it because it has a lot of synergies, and you have to plan it right because it could hurt you, too...such as undoing your procrastination.
I think this is way overpriced, though. I was thinking more like 5/2, 4/2 upped. Prefer it as a permanent rather than a spell, because one turn of it really isn't a big deal, probably not worth stocking.
