Player at LGS builds decks "to annoy people"

Hey all,

Just looking for some advice. I'm new to the commander scene so I'm pretty ignorant to the types of people who frequent LGS casual commander sessions.

I've got 2 upgraded precons and three home brews that are in development.

One crew of 3 childhood friends I play with basically just do upgraded precons and it fits my deck levels -- I'm on par with them and it's always fun.

I do jump into the other crews with more powerful decks and tend to hold my own, playing cards when the moment is right, good threat assessment, making the table more even until someone wins because I'm here to stop one player from destroying everyone. I've been getting second place a lot and that's fun... I do have the desire to figure out some more win conditions from my decks but I'll take it.

There's this one guy at our LGS who's entire mission each night is too pub stomp. Us three will say yeah let's play some decks we're developing and he'll be like: "yeah I'm developing this deck too", while not a lie... his deck is going to mess everyone up and he knows it. He's using the social construction of "all decks are being developed and therefore I'm not lying". I find this sort of linguistic lying tiresome personally but he is technically correct in his statement.

So the petty part of me is going to target him evertytime. I texted my friend who taught me magic and I was like "I'm going to build an az control deck just to mess with him"... but after some thinking... I'd rather keep workshopping the decks I want to make better.

This weekend I was playing in a pod next to him and over heard him saying: "I build decks to annoy people".

TLDR: Do I just avoid playing in a pod with this guy or do my best to target him and teach him a lesson on being annoyed.
