Despite the lack of knowing many of the actual cards, Wizards is teasing us again about the upcoming Alara Reborn set. On April 2nd they released a listing of each deck and deck list for the intro packs in the Magic Arcana section (original link), but the Alara Reborn cards are obviously not findable in Gatherer. Here we've linked cards already released and left new ones unlinked.

So what's interesting here?

1. Each of the intro packs have identical mana structure. Given the universal gold theme of the set, each of these decks is two color with 8 mana of each color, and 2 Terramorphic Expanses.
2. All color pairs are allied colors. So we see Red/Black, Black/Blue, Blue/White, White/Green, and Green/Red. No enemy color pairs.
3. We get a strong sense that we'll see Terminate reprinted, as well as a few other suggested possible reprints.

Here are the provided decklists. Any unlinked cards are cards which will be released with Alara Reborn.
