For those Blog readers who do not wish to see any Conflux spoilers, you are certainly at the wrong site. I would ask anyone who can properly translate the article to send me an eMail.
Anywho - Here is the unofficial summary of information gleaned from page 38 (sorry - no card images) . .
Exploding Borders 2RG
Search your library for a basic land card and put that card into play tapped. Then shuffle your library.
Exploding Borders deals damage to target player equal to the number of basic land types among lands you control.
Fiery Fall 5R
Fiery Fall deals 5 damage to target creature.
Fusion Elemental WUBRG
Creature - Elemental ?
Sedraxis Alchemist 2B
Creature - Zombie Wizard
When Sedraxis Alchemist comes into play, if you control a blue permanent, you may return target nonland permanent to its owners hand.
Stay tuned for more spoiler goodness.
