Most commons and bulk cards are low value, especially cards from recent sets
Now more cards have been revealed to show mechanics of the game and beautiful artwork
When you start sideboarding out those enchantments, the following cards become weaker: Eidolon of Blossoms Kruphix's Insight Herald of the Pantheon Starfield of Nyx Sigil of the Empty Throne Rather than play "good" cards like Elspeth and Wingmate Roc, we have Sigil of the Empty Throne, Boon Satyr, and Suspension Fields because they happen to be enchantments
Then finish with a wincon on the fourth turn when you shoot each foe for damage equal to your total costs of your stuff, save this
(Seriously, the card isn't legendary itself, and the Demons aren't legendary either.) You can use high quality Demons like Shadowborn Demon, which has a cool trigger, or other classics like Rune-Scarred Demon
While I'd like the game to be as accessible as possible, even on a tournament level, you shouldn't be able to build a $2,000 deck with fake cards and then expect Wizards to offer you prize money for playing its game
