I like the idea. Two thoughts:
1. I think the cost of the upgraded version should be 2 because it's not really all that better. You'll be glad you upgraded it, sure, because it'll come in handy; but the extra cost may not even merit upgrading.
2. Should it be ? Purify is by far the closest thing we have so far, and it's . I think either element works, but seems slightly more appropriate.
I seriously considered having the upgrade cost the same quanta for quite a while, but decided to up it 1 and here's why:
1. It costs numerous quanta to apply multiple stacks of poison to an enemy, so it didn't seem quite fair
to preserve the existence of a 10 quanta dragon, afflicted with aflatoxin, for only 2 quanta. It also seemed to me that
while using the upgraded version, a player would wait and make the most of the card by removing multiple stacks of poison.
Given the extra turns, spent waiting... 3
didn't seem like too high of a cost in an upgraded deck.
2. With the costs, the two versions serve different purposes and a given deck may find use in having both versions on hand.
One should also consider that on a per-stack basis, while less quanta efficient than the unupped version for dealing with a
single poisoning, the upgraded card at a cost of 3 quanta is actually extremely cost-effective for stacks above 1 when
compared to the basic version. The basic version is primarily intended as a cheap emergency button to preserve a creature
or a counter to the debilitating side-effects of liquid shadow. Also, as oty's and scarabs only devour once per turn, having
the upgraded version in such a deck would be superfluous anyway.
3. I don't want this card to be a fool-proof counter or catch-all, ...rather something to give players a chance to benefit from
thinking over their deck-building and draws.
...As for making Anti-Venom a water card instead. I specifically wanted it to be non-water because I don't think it's a good thing that the only effective counter for poison in the game right now exists in the water element. Also, I found life to be a more fitting element of choice because it's supposed to be the opposite of death, the primary user of poisons. Additionally, I am hoping that
by making Anti-Venom a life card, I will be encouraging the use of a dual element, forest-spirit deck. Lava Golem decks are a dime a dozen, afterall.
I hope you find my responses to be well reasoned. Thank you very much for your comment.
