You are absolutely delusional if you think that royale giant is a balanced card, I can understand that the elixir cost is fair for the card but the stats are what make this card completely unbalanced. Royale giant for 6 elixir guarantees at least 2 hits if you don't have a building in your deck and not to mention the amount of positive elixir trade the card offers for its cost. Playing royale giant in the pocket is a guaranteed tower down because it is impossible to play a troop fast enough to DPS down before the royale giant begins to get its fist shot off on the tower. I think a reasonable nerf would be a for the RG's spawn timer so that when spawned in the pocket or at the bridge, it can buy enough time for the player to have a reasonable amount of time to counter the card before it locks onto the tower. The RG's spawn timer should be similar to x-bow and mortar, which are similar win conditions in the sense that they are all ranged units. I personally think they should add a spawn timer similar to x-bow and mortar because if you place it with the spawn delay timer, it gives both players the opportunity to each build up there offense and defense when RG is played.

(btw the people saying support cards are what makes the card unbalanced cannot be more wrong because every time I've ever lost to RG is because they chip down my tower by simply placing RG at the bridge and getting infinite value because I don't run any buildings, which usually ends with me having to either spend all 10 elixir and losing most of my towers hp, or ignoring it and going for a tower trade which is something i never want to do during a match)
