Odin...

that can work as a budget option.
you can put res wave from aversa or def wave from silas on his C slot.
or just normal spurs/drive is also work.

Yeah, that works. I wouldn’t even call it a budget build. This is the standard bladetome build and I don’t know what else I would use in the A or B slot. In the C slot, any of the wave skills would be nice if you have the fodder.

Here’s mine. I consider Odin a very low priority for merges. Most of the power of bladetome users come from buffs on the unit, not from their stats. They just need good speed.

Guts' Odin is a good example. He said he has him smited into a pile of enemies and gets wailed on and then he hits back with his buffs while debuffing and refilling his health
