Need tips

Everyone I play with has competitive decks and while I've never really played with the competitive deck nor really cared about one. I want to build a commander deck but I am having a hard time figuring out the commander. I wanted to ask the people here if they had any ideas to point me in the right way.

The idea of the deck is basically knowing that I'm not going to win. But to kick start the game sulfuric Vortex is one of the main cards I want in the deck. I don't want the other players to heal and I want everybody including myself to take damage every single turn. I fully understand that with this deck I will be the first one knocked out every game but I do not care about that fact I just want to kick off the game for fun
