I really enjoyed running snorlax x with the common snorlax so u can attack when you're asleep, using special dark energies and Weavile from SW. It's an awesome mini combo there. Run some switches or warp points, his retreat cost will be insane! I'd almost run another attacker with him. He's a tad bit slowwwwww. Maybe even Luxray Lv X, free retreat and can bring out someting to munch on for snorlax..
He's got good card draw so u may reduce supporters that just plainly draw cards. Also u can run him with any color since he's colorless, so u may easily choose another attacker!:biggrin: Hes a really fun card. hope i helped a little bit!
