I used to run infinite combos with X-spell payoffs in this deck, by after a while I stopped enjoying winning with them so I cut em. I still have the Karmic-lark Ashnods loop, but I was careful to not include any sinks for the mana/life.
Over the course of my EDH career I’ve done this with a lot of decks as I generally don’t enjoy winning though combo with a few exceptions. Nothing wrong with it, of course, it’s just not my cup of tea anymore. I appreciate the input regardless though!
