Strategy

Mega Evolving swaps Gengar's ability to Shadow Tag, trapping both opposing Pokemon on the field the instant it transforms; it then stalls behind Protect and Disable while Perish Song counts down an inescapable KO. The bulky HP/Def/SpD spread lets it tank hits (like Dark- or Ground-type STABs) it would otherwise not survive long enough to finish the trap.
