AR Defense map idea, feedback.

I'm considering building an infantry mage setup, to utilize infantry pulse and "before combat" specials. Now I realize the units are only half the strategy and it requires proper setup (which i haven't thought thru yet). Any way here is the main idea,Hp with my build/ivs: Nowi(57)/ Ophelia(41)/ Bride Lyn(39)/ Lewyn(38)/ Lilina(34)

Nowi (Infantry Pulse)
Lewyn (Infantry Pulse/QP) 4 total charges
Ophelia (Infantry Pulse) 6(?) charges, overkill but because her tome.
Bride Lyn (Infantry Pulse)
Lilina 4 charges

Lewyn, Ophelia and Lilina will all have their pre combat special ready at turn 1. Lewyn with LnD, hopefully able to double on top of the special, acting as 3 hits. Lilina with DB4/forblaze.

Thoughts? this is more of a place holder for me otherwise, in case my current set up starts to fail.

EDIT: The reasoning for Nowi and Lyn are they both help with the infantry pulse set up and already have it on their builds. Nowi will just tank in a corner to stall, Lyn has Miracle and restore. Hopefully to take away status effect/debuffs.
