i like this, it's like a nymph's tear only for you wolf series, very nice....buuuuuuuuuuuuuuuuut I just worry about the cost, as I'm not familiar with your wolves, idk how well they would compare to nymphs. ik the tears is 8

and you can get some eh nymphs lol.
so I just have a few idea/suggestions
-compare how the cards are to nymphs and change the cost accordingly (especially when you don't have certain element being used)
-maybe have a creature that does the same thing (kinda like the nymph's tear/ blue nymph thing) and have it be called pack leader
-post a link on all your wolves pages to one page in which you have all the cards listed
