There are also a bunch of transforming cards in case you're worried about the cards getting stale
Flubs, the Fool I never expected to love a commander that wants you to play with no cards in your hand, but that's Flubs in a nutshell, and he's the real deal
The Lord of the Rings: Tales of Middle-earth Elven Council Commander Deck set includes 1 ready-to-play Green-Blue deck of 100 Magic cards (2 Traditional Foil Legendary Creature cards, 98 nonfoil cards), a 2-card Collector Booster Sample Pack (contains 1 Traditional Foil or nonfoil special treatment card of rarity Rare or higher and 1 Traditional Foil special treatment Common or Uncommon card), 1 foil-etched Display Commander (a thick cardstock copy of the commander card with foil etched into the card's border and art), 10 double-sided tokens, 1 Helper card, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card
Notably, ability stickers (and other granted abilities) aren't part of the rules text that get exchanged
So that's your Myrs getting turned into something, and all your Treasure or Clue tokens also swapping forms to something new
