>>39141744>fuck team preview, killing any potential this dude hadEven with team preview, he's still pretty beast just because of the psychology. Just having that "what if" in your back pocket while you stash your Zoroark for late-game makes people make questionable decisions.
You can also abuse team preview to make people do dumb shit. Place Zoroark up front in the lineup and opposing leads start doing predictable shit. Place your least-likely illusion in the back, something safe like Rotom-W and you will get free turns for days.
Really, it's fairy types that did him in. He used to have such amazing synergy with fighting type Pokemon like Heracross, Conkledurr, Infernape, and lots of others. Now pretty much Lucario is the only reliable partner with fighting types. He still plays well with Scizor but also part of his problem is Focus Blast having 70 accuracy. Give him a 100 accuracy SpAtt fighting type move with some punch and he'd wreck Heatran so hard.
In another metagame he has the potential to be a monster in the right hands but you have to be on top of your prediction skills. He's probably the most high skill cap pokemon ever, really rewards you for prediction.
