Fell Robin build

+spd Celica is very nice and I'd recommend to keep and train her up. Robin's A skill could definitely be a stance or breath skill if you have a free one, especially if V!Ike wins A Hero Rises. Another set of skills are close/distant def, brazen skills, bond skills, boost skills like fire boost, svalinn shield to stop effective against armour weapons like Thani, and lastly, simple stat up skills like attack+3.
