~Here possibly are two new (spoiler) images from Conflux, the second set in MTG's Shards of Alara block.
These are scooped from the 'Colors' section of the 'Multiverse' Wizards page.
~First up . . .
Mr. Nasty filagree cloud guy. A blue-centric Esper critter. Could it be possible to have an artifact avatar ? Perhaps an Elemental ? Not exactly certain how an Sage-Artificer would have an avatar creature sit still long enough to get their etherium infusion at the Esper spa.
~Second . . .
It's a Drake. Armoured with a spiked tail. Another blue-based critter. This image suggest that a Bant armourer went to town to outfit this lesser dragon.
Although these may be either alternate art pieces or from less-circulated cards, I really do not recognise them so I will assume Conflux unless otherwise informed.
Please drop me a line if you know what these may be.
