“Perfect imitation” An imitation at best but still not the real thing. Wouldn’t that just be illusions but like 3D? Like he can create Excalibur or something but not have the holy power it contains. Or maybe he can even imitate that... So really he just copies something but in this case he can copy infinitely, flexibly, and “perfectly copy” whatever he thinks of. Then I guess the only limitation is that the copied thing had to have existed and if that’s the case then can’t he just “copy” the. reincarnation?
