Hi first post on here. I wanted to post somewhere else but apparently you are not allowed

I am new to vintage and am only getting the chance to play now as a store is running a 75 proxy tournament. I am pretty excited about this.
The event is this weekend and I am pretty sure I want to play Grixis, just trying to finalise the build. It will probably be strix/welder as I like what they do.
I do have some temptation to play Bomberman as I have seen it putting up a lot of good results except it is nearly always the same person.
Is Bomberman that good a deck or is it down to the player? I played some games with it and it feels kind of clunky. What is the advantage to playing this deck over Grixis?
