I have a love for decks with sacrifice themes and Zombie tribal decks. Innistrad: Crimson Vow has an interesting new tool for these style of decks: Fell Stinger

Zombies’ strength as a tribal deck has always been its ability to outgrind midrange and control decks. Fell Stinger seems like a powerful card draw effect when paired with cards like Gravecrawler, Jadar, Ghoulcaller of Nephalia, Geralf’s Messenger and Undead Augur. It also gains a lot of power when paired with Aether Vial, allowing you to play it as instant speed, potentially in response to a removal spell. It’s also nice that Stinger can deal two points of damage to close out the game a turn early. 

Here’s a draft of what the new Modern Rakdos Zombies might look like:

4 Undead Augur
4 Swamp
3 Goblin Bombardment
4 Geralf's Messenger
4 Gravecrawler
3 Mayhem Devil
4 Aether Vial
3 Cryptbreaker
4 Cavern of Souls
1 Castle Locthwain
4 Carrion Feeder
3 Blood Crypt
4 Jadar, Ghoulcaller of Nephalia
3 Verdant Catacombs
4 Champion of the Perished
1 Urborg, Tomb of Yawgmoth
4 Bloodstained Mire
3 Fell Stinger

3 By Force
4 Leyline of the Void
3 Chalice of the Void
2 Terminate
3 Damping Sphere
