I appreciate that it takes a long time to create new cards and balance them as well. And I liked how you added zappies with the hunters but electro valley feels really empty.
Even if cards are released 1/3 as often I would rather you bulk release cards to make the game much more interesting. Because when a new card is released I play the challenge, I slowly level it up, and then might see it a bit in my opponents deck. This isn’t that exciting. If they were released in bulk (4-6) then it would spice up the meta and loads of new creative decks would appear.
I hope the Clash royale team sees this and takes it into consideration.
