All troops can be obtained, except for:
*The Imps from the Primal kingdoms, which are seasonal (so only 1 at a time is available depending on the season)
*There are six troops which can currently only be obtained from guild wars so they aren’t in chests. They will, however, be available in guild chests at some point.
Unfortunately there are many hero weapon cards which can’t be obtained. These were previously available for glory purchases as one-off events. The Devs have been making one per week available as an in app purchase. Unfair? I agree!
@Whiskeyjack is right about the Primal, guild war troops and old weapons (the weapons are periodically obtainable via real money purchases only)
here is list of cards in console:
im not sure how it goes in console but when in the pc/mobile a new troop is released via “weekly event” - that troop doesnt go to gold/glory/gem/vip chests until next “monthy chest update” happens (where all the event-troops from month ago are getting added to those chests)
i think console could have some “delay” similiar to that
so in a way certain troops may be not obtainable for a while after their initial release (they can still show up in event chests depends on the event kingdom) - but that may require someone from console to confirm that (im only a pc/mobileplayer)
