I did recommend Sash Blaziken in our DW sub-forum and I have it on a team of mine. You pass to Yache Garchomp and you're in a good position to survive the attack because the opponent doesn't always expect they have to deal with those boosts for much longer in sand.
I don't know if it's any better than Air Balloon because I enjoyed using this Tyranitar with Focus Sash ever since Fear was discussing it with me back in Gen 4. Regardless, Lucario and Salamence ususally required Life Orb to give good players' teams moe firepower to break through the opponent's team.
I guess because Dream World was new for me when I built this team, Genesect just appealed to me seeing as we have three unreleased Pokemon exclusive to Dream World tiers. It is the most replacable member of the team, but Keldeo is generally more suitable for sweeping; I prefer versions of offensive Suicune in Adv/DP OU more so than Gen 5.
Thanks for the comments guys, appreciate the luvs <x3
