Travel Preparations is a Common from Innistrad, and is part of the reason some people are assuming that this will be another three color format like Shards Block. For 1G, you put a +1/+1 counter on each of up to two target creatures. A little awkward wording, but it means you can put one +1/+1 counter on up to two creatures, specifically worded so you don’t have to put two counters on two target creatures, meaning you can use it if you only have one guy instead of giving your opponent a +1/+1 counter. Also, this will see play if Illusions get more cards in this set, as you can pump one of your guys and blow up an illusion as long as they don’t have Lord of the Unreal on the board. The best part is that it has a flashback, which is only 1W; much cheaper than the other flashback costs we’ve seen so far in the set. Having flashback means you can potentially spend 4 mana to pump 2 creatures by +2/+2; seems cost effective to me.
The main reason people are assuming 3 color decks are coming back is the fact that NayaPod and BantPod (decks that utilize Birthing Pod) are seeing significant play at FNMs and may see further play as we go into the new format, Cawblade no longer in format without Squadron Hawk. As we’ve seen so far, the set promotes multiple colors, but doesn’t have much for multicolored cards so far (aside from Olivia Voldaren), so the rest of the set will tell.
