This deck has 16 ways to get more cards, all of which sit on the field doing it painfully slowly because that's the burden we've chosen with this primal surge nonsense
The only pure Sea Serpent archetype is Atlantean, which is often paired with Mermail
The Ur-Dragon is potentially the most powerful Dragon commander with its 'eminence' ability making the rest of your Dragons one generic mana less to cast, even if The Ur-Dragon isn't on the battlefield
Most secondary Commander products, like the Zendikar Rising or Kaldheim decks, consist of only two decks
