dude I keep KOGING with Kycoo the host Destroyer and that card is more than 1 year old, sooooooooooo.........It's safe to say f2p never left this game.
I saved up gems for like 4 months and used a UR Dream Ticket and now have 3 Simoon/3 Black Whirlwind Blackwings. F2P players can still get KoG easily, you just have to be more careful with your gems.
