Feedback on my Glarb, Calamity's Augur deck? [Fairly New]

Im still pretty new to deckbuilding, and pulled a [[Glarb]] in a booster pack and wanted to build him. Was a bit confused on the direction to take him at first and ended settling on a frog/landfall theme, mainly because the gitrog frogs seemed to fit well into that theme and i enjoy the frogs quite a bit. The main thing i'm worried about is my land count and mana base, and the overall effectiveness of the strategy, as it can feel a little slow during testing. Any feedback is greatly appreciated
