Embereth Skyblazer is a 4/3 Human Knight for 4 mana, with only one Red mana symbol in its casting cost. This means that it’s at home in pretty much any aggressive Red/X deck. As long as it’s your turn, Embereth Skyblazer has flying. Being an aggressive creature, this makes it a lot more deadly than it appears at first glance.
It’s the second ability on Embereth Skyblazer that’s most worth paying attention to. Whenever he attacks, you may pay 2 colorless and one Red mana. When you do, creatures you control - himself included - gain +X/+0 until end of turn. X equals the number of opponents you have.
While a gain of +1/+0 is impressive enough across the board in go-wide strategies, the power of this card in a multiplayer Brawl game - or traditional Commander game - is immense. The lack of Haste may hold this card back slightly, but there are ways to give creatures haste. If Skyblazer could attack immediately on its own, no one would’ve been overlooking this card.
But, on Magic Online, the power of this card is quickly becoming clear. Competitive Brawl players have discovered the Knight’s value in Sir Gwyn, Hero of Ashvale decks. The Knight Tribal Commander is already a strong force in Brawl. While he loses some weapons in the November 2020 rotation, he doesn’t lose most of the Knights, especially those in Throne of Eldraine and Theros: Beyond Death.
Embereth Skyblazer may not be the most valuable card as of this writing in April 2020. But, this is a Knight to keep an eye on. It’s especially worth nothing that like some other Knights in recent memory, he doesn’t need to be part of a Tribal deck to realize his true ability. Keep the Skyblazer in mind for when rotation comes to call!
