To be fair, this is a set where four cards can be a cycle: one for each faction. The two colored DFCs we have so far are closely tied to the Legion of Dusk (the Temple) and the Sun Empire (the Cradle), which means that - if rares and mythics are all completely equalized - the Red rare could be tied to the Brazen Coalition, and the Green mythic to the River Heralds.Quote from thatmarkguy »
Don't think it's a cycle. From the rare sheet alone there was 1 fewer rare in black red and green, and one fewer mythic in green. It is largely suspected those are all evened out with the DFC rares and mythic(s). The fun question is, if Cradle is the green Rare ... what's the green Mythic?! Lotus Vale?!
If they plan this as a cycle, white and blue are likely in Rivals.
...and based on the accidentally-fully-spoiled Ixalan map, we can feasibly put names to the "land" sides of those cards: Spitfire Bastion for the Red rare, and the Deeproot Tree for the Green mythic. (Both are locations with English names that are obviously connected flavor-wise to specific factions. Seems like a logical guess.)
