Standard early-mid Elf petdeck.
The buff to
Lethrai Hideaway definitely helped. A lot. A turn-3 4/1 dark elf catches a lot of people by surprise, and can sometimes bait removal for a vanilla unit.
Shadowlands Borderscout is a total baller. The draw after a single buff from Hideaway is absolutely bonkers, and is a potent Scream target, making it a nice situational blocker.
Champion of Cunning is a VERY fortunate tribal pick, and plays its end-game finisher role perfectly.
Zende, the Heart-Binder is a candidate to promote to a 4-of because of pledge, but with 6 pledge cards in the deck already, 3 seems sufficient. I'm tempted to cut a Rhysta for a third
Elder Astrologer for survival, stabilizing or some big card draw on Borderscout, but two makes enough of a surprise impact most games.
But the surprising MVP of the deck is Lehtrai Skystrider. The mill can help land a more potent Zende summon, even if you don't grab spell, and the helicopter buff to your entire unit roster is disgusting. Failing that, buffing
Heirloom Seeker gets really scary by turn 4 and demands an answer.
Do not be afraid to block aggressively.
