Some moves I made based on Link:
Neutral b - Nidhogg: In Monsta Honta Chrom wields that bow, also he has the archer class.
Side b - Hand Axe: a heavy boomerang.
Down b - Javelines: lol
He can use the Fire Emblem shield too in Monsta Honta without his Great Lord design. But I am pretty lazy to think moves with that right now. Well this is my real moveset.
B moves
Neutral b - Exalted Falchion: a chargeable attack (Falchion's glow effect included), the trajectory is the same as Melee Marth's Shield Breaker, hitting with full power is an instah-KO like Roy and Ike, but the Exalted Falchion heals 20% of Chrom's damage, it's not unbalanced because is pretty unlikely to hit anyone with the fully charged move anyway.
Up b - Critical animation: pauses for a moment, jumps a considerable distance and strike with Falchion, it could be vertical or horizontal ala Kirby's Up B in Project M or spacies Up b.
Side b - Aether: Sol and Luna in two strikes (ala Link's forward smash in execution), the first one is a sword uppercut and heals half the damage deals, the second one is a...emm Ike's Quickdraw? i don't find the word to describe the animation, anyway the strike reduces knockback resistance and shields to half.
Down b - Counter: its tradition. His animation could be that one when he takes "No damage" from an enemy.
A moves
A: horizontal sword strike, right to left.
AA: second horizontal sword strike, left to right but more range.
AAA: jumps a little and strike with Falchion.
Dash Attack: Falchion uppercut.
All based in his Awakening's animations.
But he has more source material like lances, axes, bows, Luna skill, Aegis skill, Fire Emblem shield, the blessing of Naga, Pair Up, horses, etc. but I can't figure how to implement that things with the actual moveset I did. Ah, and I can imagine him punching and kicking like Ike.
Er, sorry if I make some mistake, write a lot in other language is a little difficult.
