Considering the resource to damage ratio and the difficulty of getting the enduring keyword to proc, this seems kinda weak. Fun idea though.

Wow, my comment makes absolutely no sense now. I need to start doing what some other people do, and quote the current effects in my post.

Dragon Nest (15g, 15r)
Dragon.
Dungeon +1,
Magic +1.
Next card will be a rare Dragon.

I feel like this shouldn't have the Dragon keyword, since it's not a dragon itself. Also, I think it's too expensive. Make it 10/10, and keep the effect, and I think it would be well-balanced. Really nice picture.

Ah, the previous version was enduring(120), that's the reason why it has the dragon keyword (a small chance to summon itself), I forgot to remove it.
changed as suggested.
