I like the card, but I think it's a bit expensive...
Wait, you can't change crucible cards? Isn't that the point of the crucible?? To change cards and make them better as you go?
Kael said somewhere:
"any modifications to the card from now on will cause the vote to be reset because the new card may not be the same as when people voted for it before and they may not like it anymore"
Also I presume if you change it after you get to forge (level 2) then it will go back to smithy (level 0) or crucible (level 1) (although this is just what I feel should happen unless it is specified)
No - the smithy is for basic designs to see if your card is good and works and for people to comment on
once you enter the cruicble you should only make minor adjustments based on people's opinions/comments but nothing major (e.g. changing cost to summon down or up by 1 = minor..... changing ability of card = major)
anything major that changes (in Kael's opinion) he said would reset the vote on that card....
~~EDIT~~
as Deadly Neurotoxin is already at level 2 (Forge) it should be left as it is unless there is an overwhelming need to change it....
