If you really wanted to cover all the bases, you could add 9 more cards that, according to my research, are rarely but occasionally played competitively these days: Arrogant Wurm, Beetleback Chief, Bottle Gnomes, Fyndhorn Elves, Order of Leitbur, Order of the Ebon Hand, Portent, Shield Sphere, and Whispers of the Muse
They usually pack high defenses, damage reduction abilities, and sometimes Energy acceleration tied to durability
If were going to see more locations, having a character with 5 Strength is super beneficial, and it can sing every song in the deck
What's more, Hasbro is working on a Magic: The Gathering film and TV series too.
Axgard Cavalry Axgard Cavalry gains points in my books for being a cheap haste enabler
For now, though, think of like this: You have inevitability if your deck is powerful enough that you'll win a very high portion of games that go long
