it should give 3 mana, instead of it it doesnt give any mana but messes your mana bar
ie you had 28 mana. and it was full mana bar. now you have same 28 mana, but your mana bar looks like its 1/10 filled only. purely visual effect. APART from the fact that invida sin with it has like 172 mana. so something weird with values probably.
cards doesnt work at arena, at arena all looks fine
effect started appearing after i got card from pending
if i take a fresh undressed group from stables effect is the same
it looks like its the card
EDIT: tested it by throwing card out, yep its the card
