Jeskai Geist

After playing with the this deck now for a while, I keep encountering miments when the deck can’t quite finish the game, the ground is too gummed up for geist to attack, and the answers dont line up to the threats. My meta consists of pretty much everything from home-brews all the way to the top tier decks. So, I was wondering if anyone can give me some advice on the deck? Or if anyone else has these problems with Jeskai Geist.
