btw I love to use amaya against cards that can't hurt you quickly (like ubuntu, popo etc) and spamming shadow curses. Might not win manny games but it's very fun to frustrate your opponent.
I was playing with a friend in un-ranked and his curse of juju (95% iirc) missed 3 times in a row and I missed once too (and they had no hit debuffs). Talk about unlucky.
