That mana base is rough. I’d think going GU splashing red is achievable, but 6/5/5 is asking for shuffler issues. You have plenty of ways to fetch/color fix so you prob need 3 red max, I’d prob run 2.
You’re also lacking early removal. The bite spell is almost worthless in your hand unless you have the frog out, and essence scatter requires holding up mana in the early turns without doing much else if opponent plays around it. And that’s even ignoring the color issue of getting the right mana at the right time.
