I'd be up for commander but I think we need 4 players at least or it would just naturally become 2 vs 1 as soon as someone gets an advantage.
What decks do you like to play card?
Yes that is what seems to happen most often. It's sort of like Munchkin in that way, 1 ahead player is beaten by the 2 behind players only for the player most in the lead to then wipe out the weakest one. Such are the perils of any multiplayer game however.
One of my decks that I'll never forget was my Norin Chaos deck. I dismantled it because it stalled the game way too long and never really won until I pulled out the "fun" Chaos stuff. At least it taught me a lot about the more esoteric portions of the rules.
Right now one of my favorite decks is a Thantis, the Warweaver one. It likes to grind down my opponents by destroying their creatures and turning that destruction into damage. One of the people I played against it described it as "Jund enchantment control" Another fun deck I built recently was Noyan Dar, because animating a land into a 15/15 is hilarious. I've got a Rosheen Meanderer that is fun some of the times. I think those are my most played decks, I have others that I less frequently so they don't get as much work put into them.
If we wanted to do a different format (like pauper, modern or something else), I'd have to look somewhere for inspiration. A combo or value deck that wins on one turn after going to 1 sounds fun.
