UB Deck Cohesion Issue

Most of my issue with UB, particularly the commander decks, is their lack of availability on MtGO, as well as their lack of cohesion at some points. Individually, the cards are absolutely flavor wins, but as part of a precon they really don't work cohesively. Take the Timey Wimey precon for example. That deck was absolutely pulling itself in different directions by trying to be time counters and investigate, and then several cards that had nothing to do with either strategy. I would have been more satisfied had the deck been all in on the time counters, rather than trying to split the deck's strategy.Another example is the Ruinous Powers 40K precon. It had a very heavy demon theme, but it was split between demons-matter/aggro and cascade/spellslinger. Flavorfully each card is an absolute banger. But the decks as a whole really lack a real focus on one or the other. An example of UB doing well is the LotR set as a whole. It allowed for flavor wins while still keeping themes appropriate for its strategy, with blue/black/red being heavy on amassing orc armies and buffing orcs, while green/blue was focused on scrying and payoffs for scrying. Flavor wins, while still keeping a clear focus for deckbuilding.

You’re comparing apples and oranges. A preconstructed deck has different limitations than a randomized product.
