Speaking of equipment, Mask of Memory remains one of the best ways to draw cards in Commander, period

AC02-JP005 Dice Dungeon Field Spell Card (1) When this card resolves, you can add 1 Dimension Dice from your Deck to your hand

In other words, even if you can't use the (1) NS effect, if you have "Derricklane" or "Bullet Liner" in your hand, it serves the same role as "Express Knight", so it acts as a 4th to 6th copy of "Express Knight"

So sending them back to the deck is not the best use of them, even if it is to draw two cards

Royal Treatment isn't entirely a one-off effect since it grants the Royal role, with ward 1 being appreciable protection after the fact and +1/+1 being a fine boost for any trampling threat
