Very minor spoiler posted at an online game store:
The left-most card is an Enchantment with the same art as the box cover. Looks like "Astral Anchor," which might be like a [mwcard=MW1E16]Force Hold[/mwcard] that prevents teleport, magically binding a creature to a zone or object?
The second card is an Attack with cost 12, full action, looks like it's called "V'Tarian Energy ___" or something like that. Ranged attack. Might be wind related (from the art).
The third card is a Warlock only legendary creature ("Skeelax, Taunting Imp"?), costs 11, Flame -2, quick attack of 2 plus a condition roll, has a defense and (1?) armour, and given the name, this could be similar to the Beastmaster's [mwcard=MW1C33]Sosruko[/mwcard]. Hard to make out the text but definitely says something about Regenerate 2 (in bold). Maybe:
"During the upkeep phase, when Skeelax is in the same zone as an object with a Burn condition (?), he gains the
Regenerate 2 trait." Or maybe "
revealed enchantment" "Dark conjuration"?
*edit*
Also included a brief description of the expansion:
"Mage Wars Battlegrounds Domination introduces new "puzzle cut" tiles for players to create their own custom Arena layouts as well as new scenario play for Domination mode, where players vie to control powerful V'tar orbs in the Arena, granting them new powers and abilities!"
