I play EDH every friday night at my place, with my friends, and it's the highlight of my week. I got 3 pet decks I cooked up.
-Florian, Voldaren Scion
The commander is there to give me some card advantage or potentially just look through my entire deck for that one card. I play cards like Pox, Fraying Omnipotence, Havoc Festival, Descent into Avernus(play that with last laugh for infinite lulz), Furnace of Rath, Spiteful Visions, Dire Fleet Ravager, Everlasting Torment and Heartless Hidetsugu. I got all the cards I need. I'll take half your life turn 3. I make 50/50 crypt born horrors. Fuck you.
-Evra, Halcyon Witness
I gain life and play Test of Endurance, Approach of the Second sun, Felidar Sovereign or Celestial Convergence. Now for the lulzy part: I play cards that stop players from: Playing more than 1 card a turn, playing anything untapped, attacking me, dealing damage to me, targeting me, targeting my permanents, activating abilities... the list goes on. You can't do shit. Fuck you. (Don't worry I don't play this one regularly)
-Jarad, Golgari Lich Lord
This is my ol' reliable. I just play creatures and blow up a big one somewhere around turn 10, if my graveyard is full and everybody is tapped, I unholster jarad and give em' the ol one two knockout.
Sometimes we play two headed edh, often we play with 5 or 6 players, sometimes we planechase. Sounds to me like the problem for you guys isn't the game but the people you play it with. Get better friends.
I've only bought boosters for other people. I get my cards on bazaarofmagic.eu. I've spent plenty of dough lately to put them into decks that would probably make a competitive player's toes curl, but around here we laugh at competitive edh. Sure, three of our players have bigger collections and play stronger combo's but nobody overdoes it and we all have a great time because they're bros. Everybody who comes around to play has their own unique and flavorful deck.
