You also get useful staples and easy upgrades in the same shell, so it teaches core Commander fundamentals while still feeling powerful out of the box
Another thing thats possible is to sacrifice two tokens, ideally Treasure tokens youve got laying around, to put an big artifact into play from your graveyard, getting powerful cards like Myr Battlesphere or Wurmcoil Engine
