Best shrine would be intimidating there is this ed + ds roll on it, its better than weird shrines. Increases odds of getting high enhanced damage, and this is a problem, you often get axes only with max damage roll, and then you can't even mo it up to 200% (which basically means bricked craft). But if you play twinked with trading (including trading for shrines) you can just buy su labrys, or eth base for runeword. Whole point of cheap craft is to use all remaining shrines and just miss that little bit extra you would get from intimidating shrine.
For MF you just would want mf rolls on your armor rolls, they can have that affix. You can use few MF runes too technically.
Ideally stack mf via merc, you can build really strong A1 merc and it will land most of kill shots, and mf from merc gear stacks with your mf then.
