I know that this set is reasonably well known, but I am not a fan of it at all. While it might be an extremely easy bluff to pull off, this is largely because it isn't a very rewarding bluff to pull off either most of the time. Keldeo is a pokemon with one extremely powerful STAB and horrendously weak coverage moves. Doesn't sound like expert belt material at all.

However, I do actually really like all-out attacking keldeo. I just feel that its STAB is too weak with expert belt, and its coverage moves barely manage to outdamage its STAB, even when the STAB is NVE if in the rain (unless the coverage move is 4x super effective, and then you probably don't even need the ebelt anyway). The best items to run are, in my opinion, Life Orb and Mystic Water. You can still pull off a bluff reasonably well like this - you use a weak coverage move to bluff scarf, and then hit them with a massive hydro pump when they least expect it. LO 4 attacks keldeo, on the other hand, is basically just impossible to wall. It just kills everything.

As far as coverage is concerned, do you not want HP Ghost or something to hit counters like Jellicent/Latis/Slowbro or whatever. If using LO this is definitely the way to go. Maybe you just don't do enough with ebelt, I don't know. Edit: err yeah HP electric is better sorry!

edit: oh, and take out that thing about bluffing specs in the rain, unless you want to add the proviso that you must OHKO your target (and then I presume you probably don't need to switch moves anyway).
