Reaper death god- edo tensi question

[Garuda4]

Quick question... If souls in the Reaper death god cannot be summoned by edo tensi, who was in the third casket oro tried to summon to attack the third? We assume its the fourth but his soul is sealed.

It was Minato, the 4th Hokage. It failed because his soul was sealed in the death god.

Minato, his soul was already in the death god so he couldn't be summoned.
