Edo Tensei was talked about being his technique back when Orochimaru fought Hiruzen in part 1. Then you also must remember that Minato talked about how Kamui was more versatile and better than him and the Second Hokage's space time techs. So Kishi had it wrote down already that Tobirama had Space time techs and Edo Tensei, I don't think he had FTG down as Tobirama's space time tech though. Either way Tobirama died fighting 20 elite, powerful, specialised Kumo Ninja.. for all you know they could have drained his chakra or something. Just because he wasn't shown dying doesn't mean it was bs it means that it needs an explanation for us to understand better.
