I am potentially assuming the Gyarados set most frustrating to Lucario would be Rest Talk, but whatever, Gengar can still get safe switches off slow U-Turns, or well timed double switches. IIRC Mega Gengar might even outrun Gyarados at +1 (don't quote me, I might very likely be wrong). Dragonite might be in a similar boat, and STILL doesn't exactly get a free set up due to again, the possibility of a slow U-Turn (and ignoring SR as a hazard). Even if, by some miracle, your Dragonite survives my powerful hit, and Gengar goes down (remember I always have Destiny Bond as an option so long as I am faster), I prolly weakened you enough for Lucario to sweep anyway. Like Jas, your missing the point, its not really at all difficult for Mega Gengar to come invia slow pivots / double switches, and you can get its only going to come in when its sure it can pull off the trap kill 100% of the time. Its sure as HELL not switching into Earthquakes, so im not understanding what your on about there, and its even acceptable for me to sac something, bring in Gengar, trap your wall stopping my Lucario, Destiny Bond and take something else down with me, and then use my Lucario to clean sweep now that your counter / check has been eliminated. Not to mention that in many cases, your stuck attacking off the bat. What are you do assuming you get Celebi / Slowbro in, spam Psychic all of the time (NO TIME TO HEAL MUST HIT GENGAR) and hope you hit my switch. Assuming obviously, that I don't just bring in a psychic resist instead.
