I realize I haven't explained myself sufficiently in this post, so I'll add a small clarification.
They're getting so much value in current Clash Royale meta, i said remove them, but it was not a good idea, but making this card getting the minimum possible value for 1 elixir is just feels better for me, evo cycle system is still same(who cycles the card first gets the Evo first) and heroes available in every time you use the card, this is why I think skeletons should get a nerf, normally I don't have a problem with skeletons but they're giving advantages to cycle these things, and sometimes works so good, I mean if you made a new deck and you need 8th card for filling the empty slot, skeletons will save your day 80% of the time, one of the few uncounterable cards in the game, easy to use to distract something etc. and I know that skeletons is not the biggest problem but when you think more, they're making so much thing for their cost, if the card staying in 1 elixir, they should only get advantage from their cost and nothing else.
My idea to nerf skeletons right now is dropping their count to 2, not entirely killing the card (it's already impossible), toning down cycle a little bit.
