Dead Deamon Consuming seal is his too and so far its one of the most deadly technich, and the 8 Trigrams seal he used to seal the Fox into Naruto and was even admired by Bee is his too, and don't forget the strong barrier he put when fighting the Kyubi so that no one NOT EVEN Hiruzen would interfere!
he has basically the best possible chakra control (since he created Rasengan) and he has at least one element and those two together result in A or S Rank Ninjutsu!!
And there are his reflexes, he could save Naruto with his own speed before Madara could stab him with his Kunai.
PLZ dont say FTG is everything Minato has its just wrong!! its just his coup de grâce
