Vantage and fierce strike seal seems op against every mage and Archer(except H!Jacob)

If you prefer to keep Bushido, then you should go for a special that deals damage. Galeforce doesn't get the damage boost.

Slaying, Galeforce and Heavy Blade seal should be great. He can charge Galeforce immediately if he strikes his foe down with 2 attacks (obviously if he has more Atk than the foe). Dropping from a CD charge of 4, to 0. He should double most foes anyway due to his naturally high Spd.

Wo Dao, Bushido, and Glimmer is really fun; his special damage goes really high

Slaying + noontime is the only I don't find very convincing (because if it doesn't activate on the first attack then you're missing 10 damage)

Wo dao + noontime + brazen atk/def sounds appealing on a flier team
