­Daring Apprentice + Godtumor

Tap'n'Sac to counter; and strong but cheap but costs a lot of life over time.

How about a counter that you have to pay for later? We can do that.

First off, this is awesome.

Second, this is broken in vintage. Pact of Negation wishes it was this card.

Third, this turns Disperse into a counterspell. Which is a pretty damn strong interaction if you ask me.

Fourth, Cumulative Upkeep doesn't work like that. You can just choose not to pay the cost and send the card to the graveyard. But I get what you meant. Let's all just presume this says 'blood counters' or 'doom counters' and move along.

Yeah; it's probably a bit too easy for blue to avoid the downside. Though I'm not too bothered that an environment with a proper Counterspell can have Boomerang do the same thing. In fact, the amusement that now you need to protect the thing that's hurting you is probably worth it :)

But apart from "Turn 0 win prevention" the downside probably isn't actually big enough for the point in time you're going to need it.

Also, apparantly this has "Cumultaive" upkeep; which must work differently :)

What downside? This is a 0 mana counter spell with no other relevant text. Every deck runs at least one copy, because it's also a complete color pie break

Well yeah; triangular life starting at 1 probably isn't enough to matter.

The "Anyone can use this" thing is much more of a problem. I wonder. Maybe "Pay a LOT of life, or offset it with blue mana" maybe? Culmulative upkeep of ? Yeah; let's do that. Though it's probably still "Use this in every deck" even at 4/8/12.

Maybe would have been more sensible, given the colour I made this. (I made it black for the life loss)

Actually; maybe 'doom' should further differentiate itself from cumulative upkeep by incrementing on each player's end phase?
