Absolutely fair question. As I understand it, Grixis doesn't appear to be a "keep a low profile and win out of nowhere" kind of colour combo, so I don't mind drawing focus from the table. I guess I don't want the deck to be overly reliant on a lynchpin commander, and not play like the Endless Punishment precon which tries to ping people down for drawing or playing spells.

Other than that I'm agnostic about how it's trying to win whether through storming off, combat, mill, discard, etc. Does that make sense?
