I think there are two very, very good reasons for players not to run Energy Search with Skyla.
1) No room (something even more valuable must be used).
2) While not an optimal play, most can go Skyla => Computer Search => [insert Energy card].
The latter the added benefit of allowing a player to fetch Special Energy as well, but the drawback of using Computer Search potentially for a basic Energy card instead of something harder to search out. Still, one Energy Search without additional elements is only going to snag you a single basic Energy card anyway.
Despite these two objections I have raised, there are general instances where a player should be running Energy Search with Skyla unless absolutely no room is left in your deck. One is the same reason you should have been running Energy Search before Skyla came out; you've got Sableye as a major part of the deck and already know you're going to need some help with basic Energy. As stated, I was doing this before Skyla in such decks, and I continue to do it after.
The second fact is also if you're using a deck that doesn't run Computer Search. Whether because your deck really needs one of the other Ace Spec or because you're not able to spring for one right now (a bit unlikely for the competitive set), then again as long as basic Energy cards aren't so rare as to make Energy Search nearly a dead draw and you can make room, it is quite, quite useful.
Many of the decks I play (though not necessarily win with ¬_¬) fall into one of these two, so yes despite the objections I raised I actually use this combo fairly often.
Addendum: I also have found myself fearing Hammers more often, and trying to run basic Energy card when I can, even as TecH! @_@ If I was only running a lone Prism Energy or Blend Energy anyway, I usually trade being able to use the card in general for being able to easily search and reclaim it (and being immune to Enhanced Hammer). When I run more than a single (say 2-4) copies of a basic Energy, Energy Search even as a single is often quite useful, and if the deck already had good reason to run Energy Retrieval, even without Energy acceleration Hammers are diminished in usefulness.
