It wouldn't work unless you were playing the deck. Right, so, since you can only have 6 copies of a card you can at most get 36 electrum from it. It'd make AI0-AI2 viable for farming, but taking this route is reaaaally breaking the 4th wall. This is a fantasy game and immersion is important, but... perhaps it would be possible to make this without saying what it does in the actual game? Something like "Sacrifice target creature to gain alchemy".
I actually think this could be made much more interesting by the usage of counters and conditions, but first we need to put it back into the fantasy setting.
