jmgariepy asked for things to do to +1/+1-countered creatures that are "something that you'd like either way", i.e. good whether it's your own or your opponent's creature who has the counter. The Dead-Iron Sledge ability occurred as a possibility, so trying this.

That's a good choice, but you're right that it belongs in uncommon.

I updated Alex's submission, adding Bud, and simplifying the Dead-Iron Sledge ability to a um... kind of a Smite ability... more of one half of the sledge? Oh, and I increased the casting cost because this is still one hella good common at . I keep forgetting that these guys can always target themselves... I don't know about you.

This looks like common material to me now, but the ability is probably red, black or white. I don't know if there's any precedent for this ability specifically, though (reminds me of Kill-Suit Cultist but, no, no... it ain't that either). Do we think we can bleed for this, or should we try again?

If this feels too out-of-pie, then we could do something equivalent with "Target Fungus and each creature blocking [or blocked by] it gain deathtouch UEOT". Ah, colour pie loopholes, how we love you :)
