750 archers all firing at the only target is nor remotely miraculous.

Heaven forbid if your Wizard actually took lucky in which case he's all but immune to the mundane force.

5E threads love to miraculously empower armies to perfectly engage a man sized target with its full offensive power at long range in the dark. It's just silly.
That's an awful long way to shift those goalposts. The fact that 750 troops can't beat the wizard in every imaginable circumstance in no why shows that a simulacrum of a 13th level wizard invalidates the other PCs in a party, which was your initial claim.
