Finally: Duo'd Tyranitar!
Video: https://youtu.be/up79hJFXEnM
Since the first successful Tyranitar duo done by the Japenese, I've always wanted to try it. This is hard in terms of stardust and, most importantly, another trainer on board. After the past few months' grinding, I've finally managed to pull it off with trainer polkadotjam. Together with two other trainers, EpiCrimson (fellow GamePresser) and simonyue, we formed this little group which we are proud to call "The Elite Four", will continue to seek more raid challenges!
By the way, below is the list of challenges we have completed recently:
1. Charizard Duo (https://youtu.be/xr7TAOU36r4)
2. Victreebel Duo (https://youtu.be/ukJZ-02cSJM)
3. Lapras Trio (https://youtu.be/oLefcpEgtew)

Excellent video! My first Ttar trio was Bite/fire blast and it took 2 attempts. Trainers were 33,32,27 and someone was dual-boxing the lower 2 with no_dodging. We were about 10% short with bad RNG and dodge bug. Attempt #2 allowed me (the solo device 33) to dodge and I had good luck with fireblast landing when I was at low hp already on 1-2. We beat it with 4s left. A bite/stone edge today was a joke by comparison with the same team and even a dodge bug. We have found that bite+crunch/stone edge are easy, whereas iron tail+ either crunch/stone edge to be moderate, and bite/fire blast to be hard while for us iron tail/fireblast may be impossible without perfect RNG for our teams.
Level 30 Machamp is as good as dead with fire blast (especially coupled with Iron Tail), but I tend to see my Level 37 one survive a full on fire blast. I think, if you have sufficient Machamp (that can survive a full fire blast), you can probably duo it by rejoining, but not in one team of 6.
When I build my L37 Machamp army I would like to try it some day, sadly I only have 1, the rest are at level 30.
