Elves, screaming elves everywhere.

Disclaimer: I love Haunting Scream.

I've been brewing with Scream ever since I started playing. Tried out the elf package and the deck (to my surprise) got me from Silver to Diamond 1, so far. (Working on getting to Masters, but that's a grind)

Deck isn't quite your regular "scream to the face until your opponent dies" deck, but tries to accumulate card advantage via the Gorgon Fanatic, Haunting Scream, Dark Return combo, and to trade its removal spells with the opponent's creatures until they run out of cards.

Lethrai Skystrider helps to get stuff into the void and keeps your card advantage going, it also grants flying to your elves on attack, which has closed out some games for me, too.
