I remember our discussion about these cards. I was under the impression that we had come to an agreement on how bad the drawback needed to be, including the addition of the ability to sacrifice the Cursed Mox by paying 1 life.
Whatever the CPAers decide in the end is what I'll go with (it's them I'm doing this for, not myself).
Additionally, at your request, I will simply remove them from the datafile; they are, after all, your ideas.
Here is the version you sent me.
Cursed Mox Emerald
0
Artifact
Whenever an artifact is tapped, you lose 1 life.
T: Add G to your mana pool and lose 1 life.
This is the version currently in the datafile.
Cursed Mox Emerald
0
Artifact
Whenever an artifact becomes tapped, you lose 1 life.
Tap: Add one green mana to your mana pool.
Pay 1 Life: Destroy Cursed Mox Emerald.
As I recall, your position is that the drawback must be severe enough to prevent abuse.
I am of the opinion that the original drawback (2 damage just for tapping the Mox, assuming no other Moxen in play) was so tough that it would preclude the card ever being played. Tapping the current version of the Mox will still cost 1 life per Mox in play, a savings of 1 life per tap.
