It’s almost certainly a “Legends Reborn” event/week. We typically see several troops – including a Tarot and another Legendary – plus a couple of weapons and some troop-specific pets when that happens.
Not all of those new stuff is related to a “Legends Reborn”. One of the weapons in question is the Campaign weapon and a second is tied to Whitehelm being the event kingdom starting the Monday after this upcoming one. Two of the troops are also tied to the same, one of them the Event Captain and one of them the typical Glory Store release.
It just seems like more because we haven’t seen a Legends Reborn in such close proximity to that same kingdom being the event week. Let alone both of those combined with that same kingdom being the campaign focus as well.
