I've found that commonly we look at players and expect certain things out of them/their decks. So what has your playgroup came to recognize you for?
For me it's a few things:
* In standard, when I was playing it regularly, they expect me to me a Timmy and look to ramp like crazy to drop big bombs. Occasionally I would throw them off by going speedy weenie decks.
* The guy that includes basic snow lands in his EDH decks just for grins and giggles.
* I'm also the guy that's going to do something during the game they consider "mean", like -3 Sorin with
Wound Reflection out.
* Lots of graveyard shenanigans.
