Im stuck in low arcanist how can I improve at this game?

Im currently on a 8 game loss streak in around arcanist 2 and its kinda demoralizing. Im not sure what else i could do in these games and id really appreciate the help. I mainly play Paige, Mo and Krill and Mina but also wanting to learn Pocket. Will update with more mina games (havent had too many where I wasn't carried by some friends who are significantly better) Here are some match ids:
40911128 (Paige)
40919530 (Paige)
40907629 (Mo and Krill)
40904601 (Mo and Krill)
