None of these spoilers currently have pictures to go with them, but the source is here, being confirmed at Pro Tour Phili. Feel free to catch up on all of them.

Slayer of the Wicked

Creature – Human Soldier Uncommon
When Slayer of the Wicked enters the battlefield, you may destroy target Vampire, Werewolf, or Zombie.
You don’t want to see his trophy room.
Illus. Anthony Palumbo 3/2

Slayer of the Wicked is another Flavorful card, a 3/2 for 3W that kills vampires, werewolves, and zombies. Like Elite Inquisitor, unless the tribal decks become big, this won’t be very good. However, he’s decent for an uncommon, and will probably see some play in limited.

Snapcaster Mage

Creature – Human Wizard Rare
When Snapcaster Mage enters the battlefield, target instant or sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost.
Illus. Volkan Baga 2/1

Personally, I like Snapcaster Mage. A 2/1 for 1U with Flash and gives instants and sorceries flashback until end of turn? Giving Day of Judgement or Ponder a flashback option is always great. A decent rare, but not a chase card.

Village Cannibals

Creature – Human Uncommon
Whenever another Human dies, put a +1/+1 counter on Village Cannibals.
They have endured the horrors of Innistrad by becoming the worst monsters of all.
Illus. Bud Cook 2/2

This is a card I wanted to see the art for. Cannibals? In Magic? Zombies we see all the time, but Cannibals? However, Village Cannibals is not a bad card, it could be sided if you’re playing Zombies vs Humans. But, Village Cannibals is an uncommon, and a decent one at that.

Instigator Gang // Wildblood Pack

Creature – Human Werewolf // Creature – Werewolf Rare
Attacking creatures you control get +1/+0.
At the beginning of each upkeep, if no spells were cast last turn, transform Instigator Gang.
Attacking creatures you control get +3/+0.
At the beginning of each upkeep, if a player cast two or more spells last turn, transform Wildblood Pack.
Illus. Greg Staples 2/3 // 5/5

2/3 is a little small for a 4 drop (3R) but for a 5/5 is great. Instigator Gang gives all of your attacking creatures +1/+0, and he transforms with the werewolf rule. He becomes Wildblood Pack, a 5/5 with Trample that gives your attacking creatures +3/+0; meaning he becomes a 8/5 trample when he’s attacking. A great card in my opinion, I’m hoping he sees some constructed play when werewolves hit the scene.
