I didn't say it wouldn't work, I said they wouldn't likely be able to cast it. Neither Madara nor Obito even bothered with Genjutsu against their opponents at that level, and Tobirama still defeated Izuna who was in the same power range. This suggests they know it isn't going to settle those fights, or make enough of a difference. The main thing is their most powerful illusions require eye contact and it would incredibly silly to suggest, as a prior commenter did, that Minato would just look into Itachi's eyes because reasons.
