Okay, who just said Tula is overpriced?
Dorian is extremely powerful, and Argos is right, if you give him an ability, he'll turn into a monster. I've never seen a card turn instant Cr though.
Jay's price increased by 12k when Eloxia was released. (I think we all know why.)
Although that combo doesn't work too well, it's too predictable and very easy to counter.
