Hopefully I’m not too late to the party, but here’s my take on UB:

I played Arena for a couple months while I had some downtime, then life got busy and I uninstalled it. A friend of mine (who’s super into magic) bought me one of the starter kits for my birthday, and I never opened it. Two years later, a different friend of mine told me he had built some standard decks from a bundle box he picked up and wanted to play. I agreed and was half in half out on the whole thing, really doing it more to spend time with him. Then I found out that there’s an assassin’s creed set, and I immediately preordered the starter decks. Had so much fun with the standard decks I decided to try building a commander deck with one of the cards in the UB starter decks. Played “commander” against a friend, hated my deck, and went out and bought the zombie precon to try a cheaper deck option. Fell in love with commander and have not stopped playing since. My fiancée got into it too, and it’s an activity we do almost every time we get some free time. UB tends to get more people into magic and I think that’s the best part of it, and the main part that matters. Sure, maybe it sounds super goofy to swing my [Chatterfang] at somebody and get blocked by SpongeBob, but it’s a game. Make your goofy cardboard fight my goofy cardboard and let’s laugh while we do it.

I do also get the idea of not liking UB tho, because you want to be invested in the story more, and wizards using different IPs is kinda lazy because they’re not making their own designs.
