Is the fact that all cards are from Kaldheim intentional?
If you want to play The Prismatic Bridge, you should make sure that you hit huge stuff, like
Ulamog, The Ceaseless Hunger for example. If you're on a budget, there are alternatives like
Stormtide Leviathan.
You don't want to hit a
Battlefield Raptor, since you will only get to use the ability once per turn, so it's not going to be so "fast"...
Anyway, I would start from the basics: 37-38 lands, 10-13 ramp spells, 6-7 targeted removal etc.
There are some good deck building templates around:
