Snorlax Tm

Definitely keep Body Slam

Recommend not to reroll body slam. Defenders may not be useful right now but I would wait it out till further changes. Body slam is great, not to mention it's a legacy move.

Body Slam lax is next best defender after any blissey

Don't touch that body slam lax!

If defending becomes important again - which it very well might - body slam is the best move on snorlax.

Alternatively I'll trade you a hyperbeam lax for it! ;-)

Unless a legacy move is complete garbage, I wouldn't use a TM to change it. Body Slam is definitely not that.

Rerolling BS is not a wise choice.

IT hits fast and hard and can even hit 4 times in a row.

Here are a bunch of good reasons why you should not: https://pokemongo.gamepress.gg/q-a/snorlax-tm

Are you insane?

and then they say there aren't dumb questions.

If it has lick, use a quick TM. Definitely keep BS.
