What's happen if your hand is already full?
This is actually stronger than hourglass in a lot of ways, because the only way for it to be killed is if you either kill it yourself or you have 8 cards in hand EOT. It costs more, but it's also an attacker. I realize that the entire point of this card is the Distrust ability, but with that I think it's overpowered. If you increased the cost by 1 I think it would be reasonable.
What's the theme of having an alchemist be distrustful? And why does playing it make you draw?
Just a suggestion for the ability, while "Distrust" is a good name in some ways, it comes off as too . How would "Flee" or any synonyms work, seeing, as you said, it isn't a fighter, per se.
