A hammer replaces Knock. 4E Knock isn't worth saving - let it die.
And hopefully the Rogue has a role beyond one use of one skill - assuming the party even has a Rogue; there are other strikers out there.
I like the new Portable Hole, although I think there should be an Epic-sized Bag of Holding as well. If you can't carry siege-weaponry in your pocket, you shouldn't be calling yourself a Demigod.
