Ok, so X is double the amount the damage was reduced by during the Combat Phase, and if the damage is above printed, using Healer counds as reduction for that.
My question is, let's say you REDUCE first. Does the amount X counts for remain?
For example:
Let's say that for some odd reason I have two Healers. I use a Glanzende Nova and Frischer Himmel to give it -2 and draw 1 card. So far, I've reduced it by 2, so X will be 4.
Now, assume I do a Healer. Is the reduction still 2? Is X still 4?
Now I do an Amy's Assistance for -4 damage. Is the reduction now 6? Or 4? Does damage pump/returning to printed affect what X ultimately is?
