you have not given one good reason other then Madara is hyped blah blah
Madara won't turn Izanagi on in the start of the fight he will try to warp raikage after a while and when he tries Raikage will punch him
no jutsu needed
that's what I thought as well,but in this tournament they have to win no matter what,even if they are going to die too. you can't assume that tobi won't use izanagi,we not even know him but do we know how he will fight?
Not even mentioning that Madara's intangibility jutsu is the best counter to A's attacks...so how will A punch Madara is still a mystery to me
http://www.mangareader.net/93-55464-...apter-502.html A escapes and punches tobi behind him.
Also A can't get behind Tobi he way Minato did...because Minato did it through a S/T jutsu, and Raikage doesn't have that...not to mention the fact that I don't think Madara will try to face Raikage in hand to hand combat, knowing after the first moves that A uses Nintaijutsu...
So I don't think Minato can be replaced with A in that panel...the circumstances are extremely different...especially since a few scenes before that Minato was caught in the warp...
