Jungle Synergy

Hello, I am seeking advice for what champions have the best synergy with others, I know you have synergy calculators and other tools online but I wanted more explained opinions because everyone's play style / situation / builds / runes are different and so reasons for why champions synergize in situations would be very helpful, thank you! My duo partner is a mid laner, and I mainly play with mid laners so for jungle champions I am looking to know what mid laners best synergize, and vise versa. Any builds that work particularly well to help mid laners/junglers synergize, runes, ex are also appreciated!

Champions

- Jungle - Jungle - Jungle

- Mid - Mid - Mid

Thank you, any advice, tips or information is appreciated! P.S - Please keep in mind we are complete noobs, he is Bronze III and I am Silver V but we are fine with our play styles and are gonna start climbing ATM which is why we want good mid ~ jungle synergy (to hopefully work well together and increase our win rates together!)

Once again, if anyone gives us advice thank you and I will probably reply :D
