Looks like three more Conflux spoilers, this time from an upcoming publication of the popular Game Japan magazine.
This spoiler courtesy of Tsuruda over at the MTG Japan Blog.
Artifact Creature - Jellyfish (Uncommon)
At the beginning of your upkeep, return an artifact you control to its owner's hand.
OK - So this is a 4/3 for only 3 mana - and no funky shard colours to contend with. Not bad at all and a great way to pull your other artifacts from the graveyard by returning Sanctum Gargoyle from play to your hand (rinse and repeat). There are another half-dozen Alara cards which can benefit from this card.
~Extractor Demon 4BB
Creature - Demon (Rare)
Whenever another creature is put into a graveyard from play, you may have target player put the top two cards of his or her library into his or her graveyard.
This card does not immediately scream for inclusion in any of my decks . . . meh.
~Giltspire Avenger WUG
Creature - Human Soldier (Rare)
Tap : Destroy target creature that dealt damage to you this turn.
I'm already working on nasty little synergies with this guy here and am sure to pick this up.
