[quote name='Serph']to tell you the truth no idea who is Archer[/QUOTE]
lols you don't need to
@ Gnome well true but Archer has Independent action which makes him able to surive without a master and saber at a perfect master with excailbur and avalon is a force to reckon with
UBW requires alot of mana , concentration, and the chant
Its consider the noble phantasm withe most weakness
If saber just goes brute with excailvur Archer is dead unless he Rho Aias first then uses UBW then Traces GOB to weaken saber then finish her off with Black excailbur which is not a very easy thing yet this is one of the many possibles
Since the area the fight in also proves their advantages and disadvantges
