600 crystals for 15 packs of SOI. I got like 2 new cards.
Wish I’d known a new set was coming out today. I would have saved the 600 crystals 
The best way to be informed is involve yourself more. Many players in the Facebook group, slack channel or on Reddit will probably be talking about pertinent information to the current state of the game.
Or you could just visit the forums more often. 
Didn’t realize that. Thank you!
I’m in slack & reddit all day for work. Only hit up the forums every week or so. Usually when things get buggy or a new release just came out 
On the plus side you can get a pack of eldrich moon in each event with a guaranteed rare,so pulling cards from the base set only might have it’s advantages
I got some cards today from the SOI with the new set and I got 3 new rares. I can’t complain about that.
You know, just looking back at what could have been with that 15x box.
I remember the conversation in my head “well I have all the planes walkers I care about, at least on a x15 box of SOI I’ll get something. Nothing else to spend the crystals on”…
ooh, a pack with a guaranteed rare.
Is that a standard prize or you have to fight up the competition ladder for two days to get it?
I believe you get it for completing the personal ribbon awards in events. Quick Battle does not give out EM packs (to my knowlege).
