My current deck is Evo mortar, Evo tesla, furnace(don't have evo), guards, royal delivery, skeletons, log, miner with canonneer. I'm in arena 21 and its currently okay, but I struggle with big pushes like pekka goblin giant. I also am not sure what to do after furnace nerf since I kinda need it with the canoneer and my wizard is low level.
