Alright, I'll sum this up for you in illustration form...
Kunai >>>> FTG >>>>> Kunai >>>> FTG >>>>> Kunai >>>>> Minato

-------------------------------sand------------------------------------------ Grass/whatever terrain it was prior to gaara taraforming.
Please explain to me how Minato couldn't get out of the desert?
You honestly don't think Minato could tag Gaara with a FTG seal? Are you mentally retarded?
It's the same concept.
This didn't come out as planned, but the general concept is same as above, just in a diagonal direction.
*Tag* Gaara :0 :'(
------- Minato "Hi Gaara"

(Hover) Same Kunai w/ftg
Same Kunai w/ FTG
Same Kunai
Kunai w/ seal <<
Ground>>> Minato (Oh Gaara thinks he is invincible huh?)
