2 rares for 15 gems in one turn? that's a bit too much don't you think?

actually you already have a rare in hand (power up). so this is a rare+1 card, as scepter of summoning.
anyway it's ok for me to rise the cost, maybe 20 gems?

Maybe a rise of cost would be good.

I was just about to post something very similar to this in the concepts section, except mine cost more and had the Durable keyword, so it only gave you one other rare each turn you used it, and never one from your deck.
