Thanks to KJP.
He taught me some PSA.
Moveset change differing from Ike's original:
SideTilt: 321% damage, high knockback
A couple sword moves have a fire effect.
SideSmash: Spikes them.
N-B: Ike puts his hand upward and it gives fire(5%).
Attribute: Ike is faster(Run).
That is all.
I'd say it's pretty fun.
