The Return of Finja?

Murlocs are looking pretty trash right now though. So we will probably have to wait an expansion or two before it's actually viable but still cool. 

I noticed that too. Without something like the Jade Lotus around to motivate ninja murlocs, I'm not sure what Finja would be doing in the Barrens though. Perhaps some themes/characters are going to be present from Gadgetzan (which isn't too far away from the Barrens)? Or, since rogue doesn't need a specific reason to have a ninja character, maybe the time of murloc rogue is upon us?

The art looks like its just a small part of a larger image though, so it is likely a spell, meaning Finja might not return as a minion in its own right.

Thinking 100% that's gotta be him. He was a pretty popular little guy and it's been a while since murlocs had their time to shine. Don't write them off, crabrider and flyer are solid additions!

Idk. I think it's more likely that it's a card that references him. The artwork just looks too much of that of a background character.

On the other hand: it wouldn't be the only card that could have a comeback. There's people thinking that we'll see a new Kazakus, because of some artwork having a resemblance of his belt.

Maybe they'll both return in some form?

Now I look at it, the first teaser image is actually a perfect match for Kazakus' belt, which has a bit too much going on for it to be coincidental. Maybe MSoG will have a sizable appearance after all.

Now my mind wonders back towards Iksar saying "We have the first version of a 'newer, cooler' cosmetic coming soon, so looking forward to seeing what people think." Tri-class hero portraits of Aya, Kazakus and/or Don Han'cho maybe? Man, what a slap in the face to us rogues it would be (again) if we finally get another non-Valeera hero, and have to share it with shaman and druid. I'm not sure if I'd be fuming or applauding the sheer audacity of it.

Maybe Finja will be one of the mercenaries. I know it's pretty unlikely but that would be amazing. This would make sense as we can see Bru'kan in Chain Lightning (Rank 1) (and the other ranks) and we can see someone who is presumably a warlock mercenary in the background of all the ranks of Imp Swarm (Rank 1).

Good catch! But because of missing details, this is most likely only a small part of a larger image. Could be a spell "Summon three muurlocs from the past" or something like that

Seems pretty clear this is a tiny detail on a card zoomed way in, a tactic they use all the time during reveal season. I'll be very surprised if this character is the real focus of the new card.

So, now that the new Kaz got revealed, the chances of getting a new Finja should go up, right?

Like people speculate, he could be one of the mercs. If that's the case, I'm putting my money on Rogue.
