I've been using Kadabra a lot in the current meta, because it is so much fun to play with. As scorpdestroyer pointed out, encore can stop/annoy many of its usual counters, especially those relying on sucker punch. As for being outclassed by Jynx, I don't think that is true, a portion of its roles got over taken by Jynx, for good reason, but it still has a lot of value as a catch all revenge killer, being guaranteed at least one shot before death (barring rare multi-hit moves). I have personally been using Kadabra on the same teams as Jynx, as it usually draws in all of Jynx's counters (dark types and steel types, especially those with priority), and can take them out with HP ground or Signal Beam. After Encoring a sucker punch, it also gives Jynx an opportunity to get into the game w/o risking taking a hit, set up a sub and even lovely kiss or Nasty Plot (if they continue to keep the encored mon in), opening it up for a Jynx sweep/clean. In all honesty Kadabra is probably the best teammate for mono-attacking Jynx to have for this reason. Kadabra's use does jump slightly in the 1850, in spite of it falling a few places, but it is a decent mon, and I definitely don't think Kadabra should be overlooked as an option in the current meta. Mandibuzz dropping is really more of a problem for Kadabra at this point than any of the other recent drops.
