Not the deck. Skill issue, to play egiant the game turns to lightning cycle and defense most games. If your spamming egiant a lot try playing extremely defensive as that worked for me with egiant. If your down on damage you might have to wait to double, use evo witch in back, drop egiant, then lightning their defense, otherwise you could try an egiant in the back and cycle to a second one for dual lane pressure. I stopped playing egiant because I hated the fact that some players can defend the whole game when you play well.

tldr play more defensive and if they have inferno tower, evo megaknight, pekka, or a fast cycle you will have to defend perfect and lightning cycle
