Weakness to stealth rock 4X weakness to mach punch and bullet punch Weakness to fighting, steel, ground, grass, water, and rock. All pretty common attack types. Resistant to normal, flying, ice, and poison. Ice is the only one that is worth anything. Flying to an extent, but that's really bouncing Gyaradoses, hurricanes, air slashing Togekisses, and brave birding Skarmories.
Offensive prowess may make up for it though.
Super effective against fire, grass, ice, flying, ground, bug, and dragon
