How do you feel about this?

Awhile back I saw a question about making a owl tome team, I thought this was interesting so I used a calculator to see how this would work. The best team so far is Boey, Mae, Katarina (probably spelled that wrong), and Innes. Boey would be the tank, Katarina would be the speedy unit, Mae would be the OHKO cannon, and Innes would be the mage killer and only physical damage dealer for now. Innes is not that needed but if you have him congrats, if you don't have him I recommend a owl supporter like a psudo healer or a buffer. All units will have a spur/drive skill to further buff these units. I just though this idea was cool and wanted to see what others think about it
