Oliver Lunatic GHB (using one of each unit type)

This is basically the simplest way to defeat the Lunatic Oliver Solution with one of each kind of unit, for the Free Oliver unit for the event FEH is doing at this time.
Oliver is an incredibly easy GHB Unit, and most likely the weakest in Book II's line-up. That being said, the solution doesn't work as well with Infernal, as it does with Lunatic. With Infernal, if You can one-shot the Green Mankyte, then you will be mostly set for the rest of the map. Fjorm can still sweep majority of the units, and Eir can be used to help buff Fjorm up. Heck, If you wanted to, you could give your Infanty and Armor Unit the Def Tactic and Res Tactic 3 Seals to buff up Eir and Fjorm's Def and Res, and then also fodder a 4 star Legault for Attack Tactic 3 seal onto either one. Then Eir and Fjorm would just be what you would need to conquer the entire map, easily.
