Getting a free 5 * from raid is not unheard of we have awesome units like Yshtola, Lara Croft, and Kelsus who help with farming or expeditions for most of us currently. However it has always been stated by most redditers that they would never give us a free 7 * unit let alone one we could get enough to earn an STMR from. After this current news that, yes you can, here is a lion guy and if your lucky you could possibly pull 4 of him and get his stmr(not saying its going to be easy just saying the chance is there). So lets see who could be our next Free 7 *

First up is Lara Croft. In all likelyhood they would have to replay the Tomb Raider event for us to get up to 4 of her(we got 2 free already) so this one is not highly likely currently, still plausible but low on the list. Slightly higher is the Healer Yshtola, she would make for a good candidate but JP would get her well before we see her return currently. This leaves Kelsus, our little Earth Dude with floating hulk arms. We are likely to see him return around Christmas, and he is given to us often enough that he could be another unit we will see get his 7 * before either of these banners returns. So for speculation purposes if you have a bunch of these 5 * still cluttering your bench, there may still be a use for them beyond just expeditions in the future.

TL/DR: They are giving us a free unit that can become 7 *, here is a thought on how soon we could possibly see the next free 7 * unit.
