I've seen claims that HF Shirou can Trace weapons stronger than the originals, since he's now putting every ounce of his strength into a single battle instead of trying to fight a thousand battles at once.
And now you know why Nasu said that a fight between Shirou and Shiki would end in a draw.

That card takes a too direct way of doing it I think.
The preferred way is to:
A) duplicate and equip any artifacts and creature enchantments in play or the graveyard for a mana cost
B) gain all the special abilities of any creature in play or the graveyard.
C) add a creature's power and toughness to Shirou
I think he makes them
as strong as the original and also Traces the skills associated with it, which is why he wouldn't fight Dark Saber with Nine Lives Blade Works, Dark Saber is as strong as the original and her attack power is mana based. Which means trying to beat her at her own game is suicidal.
Berserker was
weaker than Hercules due to loss of sanity plus loss of senses(it's noted that Berserker's rage+taint had gotten to the point where his senses didn't really work anymore), as Saber he'd have been totally unstoppable with God Hand, the presence of mind to evade, Saber class Spell Resistance
and use his other Noble Phantasms.
So he struck Berserker with his own full power.
I think HF Shirou vs Shiki will end with two heaps of finely diced meat, given
both their abilities to keep moving after fatal wounds.
UBW Shirou depends on if he can cast Unlimited Blade Works fast enough. The rain of swords option might do the trick, otherwise hes probably a goner.
Fate Shirou could Trace Avalon and Caliburn. Probably wouldn't help him against an opponent based on precision, speed and one hit kills.
