One of the lgs still has a mirror mastery on his shelf for 30 bucks is this a good deal two guys I know just started getting into commander and I think I might have to make the plunge
Pretty good. Mirrors mastery isn't the best of the preconstructed commander decks, but comes with some good stuff, and a few staples like {lightning greaves} and {sol ring}. The deck itself is a good starting point for sure, but will need a personal touch to make it truly shine - and you'll find lots of help doing so in the commander forums should you so choose.
Now if you see heavenly inferno for 40 or counterpunch for 50, you buy those suckers right away ;)
But $30 for mirror mastery is a pretty solid deal.
Well 30 is the MSRP so it's not like they're overcosting it. I have mirror mastery and have found it to be very fun.
