Izuna had the mangekyuo, yet he died against the hirashingiri, translated as 'flying thunder god slash' of Tobirama.
Its kishis way of showing that s/t and ftg users like tobirama etc pwn mangekyuo users like izuna etc.
No genjutsu, no susanoo and no tsukuyomi could save izuna, there was no problem like 'oh he's gonna make eye contact with teh sharingan and git caught in genjutsu cuz tobirama is'nt even an uchiha blah blah blah..' Izuna just got speed blitzed, got pwned and died.
And tobirama did'nt even need a rasengan.
Get my drift?
