What is the most OP card in Clash Royale (that really needs a nerf)? - Quora
Clash Royale' June 2018 Balance Changes: Spear Goblins, Mega Knight and More to Get Buffs and Nerfs
Orange Juice on Twitter: "What're your thoughts on the Mega Knight so far? https://t.co/VRFkJOlppB" / Twitter
I took the mega knight's usage rates right before the nerf, and compared them to what they've been over the last week. Safe to say now that is did little to solve
What I'm saying here is mega knight and electro giant does less dmg than royal giant and royal giant costs less elixir than them too...so if they want to nerf royal giant
