Today, Wizards of the Coast spoiled 1 card of the new Commander set.
Second: Heroes VS. Monsters
Today, Wizards of the Coast spoiled the 2 mythics for the upcoming Duel Decks. The Heroes mythic is the reprint Sun Titan with new art. And the Monsters have a Hydra named Polukranus.
The first part of this section will be random art.
The second part Will be the art for the three major Theros cities. In this order, Meletis, Akros, then Setessa.
Third part are the Heroes. As far as I know, the Heroes will act like Vanguards. As I have not been playing Magic for very long, I do not know what that means but I will update you as soon as possible.
Fourth part is art for some god creatures. There are 5 gods, one of each color.
Nylea, God of the Hunt
The full name is not spoiled yet, but this is Erebos.
Again, no full name. Here is Heliod
Fifth part is some planeswalker info.
There will be 3 planeswalkers in Theros.
One will be Elspeth, and one will probably be Dack. The last planeswalker will also be new.
Here are 2 Elspeth pictures.
The best part of Theros is there will be a new frame. It is depicted in a blank card of Erebos.
Sorry if this post is really big. I just wanted to make sure you were able to see all the new great stuff Theros has to offer.
