Gaara vs Oro + Hashirama + Tobirama. -___- Team 2 wins.
Why would ET be restricted? that's like restricting gaara's sand defense. Plus ET seems to not matter, gaara can seal people with his sand burial provided he has the seals.One of the main problems I see for Gaara here is Kusanagi. It's supposed to cut through diamond and can extend to freakishly long lengths. Combine that with Orochimaru's stretching neck and you gave an extremely slick blade coming your way, and that's not easy to deal with. I don't want to count Gaara out of course, and I can see it going either way provided ET is restricted. Personal opinion just makes me think Oro wins.
