It might be that your Commander struggles to enter the battlefield at all, especially if your playgroup plays a lot of blue (and especially if theyve read my recommendation to run Mana Drain more often)
One thing that's interesting, and worth considering, is whether The Deck of Many Things is actually any better in a Mr House deck than in other dice-rolling commanders like Wyll or Farideh, Devil's Chosen
Perfect For Families
This allows you to easily generate infinite red or blue mana with just these two cards
Im a little concerned about the crimps as they are slightly different
Urza's Command can drop the power of other player's dorks out of nowhere, make a Powerstone, make a tapped Construct token to win the game, and then scry and draw, so I think that the Construct and scry and card draw are the default here, and that's pretty good for four mana instant speed
