I think it makes it too reliable for the effect. Unless you drew all your creatures already you'd always draw at least one creature (for 2
/creature). Plus, if you draw exactly one creature you get the creature and can use the permanent again. After thinking a bit, how about making the skill cost 2
, but attempting to draw only one creature and refunding 1
only. That way using the skill can have 2 outcomes:
* Drawing a creature for 2
* Wasting 1
, but you get a new chance at drawing a creature.
Since it makes the card less efficient you could reduce the
cost too. For the upgrade you could then improve the efficiency a bit by making the ability cost 1
, but with no refunds (so if you do draw a creature you only spend 1
)
