Ike, myrh, nowi, ephraim.
2 dc units.
Nowi provides better support than hector.
2 armor march make it super easy to use
Generally....build around two units (or one) and try to cover their weaknesess, in this case nowi and ike. Armors biggest weakness is their bad mobility. Nowi and ike have good mixed phases but if they cant get to where they need to be and get a bad matchup because of it then they are screwed.
You could also build a mostly enemy phase armor emblem with god surtr. In which case ud only need 1 armor march and can focus on buffing with goads or hones
