Thanks, Thezzy. I had thought about making her Priest, but I decided to go Hunter because of the adventure boss. But you're right Priest is the better choice even considering that.
Thanks for feedback!
For your card, I like the priest card the most. I guess summon a copy of deathrattle minion would be more interesting, and if change it this way, the stat should be lower or cost should be higher.
And for my card, right, I miss the mech tribe. However, I think that a coin could not only gain a mana crystal that turn but also add a card to hand is too powerful, so I change it just this way. Thanks for your advices anyway!
