We all have that deck that just survives even though it isn't the best. For me that's [[Torgaar, Famine Incarnate]]. It's not the best mono black commander in any way but its particular combination of effects to me is emblematic of mono black. It's a bit of a swiss army knife and so I find myself hard pressed to really change anything about the core of the deck.
I built a [[Multani, Yavimaya's Avatar]] $50 budget deck a number of years back that is just a mono green spell slinger build. It is pretty simple to play for new people and resilient enough to play with my normal group.
Being a budget deck I even run it unsleeved and get that nostalgia of playing kitchen table magic as a kid.
That sounds great. I care about the new player experience as well and it's cool to see such a "what you see is what you get" commander get some love. I need to pick one up, actually.
