Disclaimer: I am new to competitive, this was my first team created via a lot of experimentation, I only hit master recently (Building this team along the way as it was countered in real time)
The three core members of this team are Abomasnow, Baxcalibur and Cetitan, I brought them every time. Mismagius was for countering trick room, Frosmoth was for dealing with Ghouldengo and hazard teams, Grafaiai was used anywhere else (also very helpful vs Torkoal to refresh snow w/ parting shot).
Entrainment would mainly come into play later in the game after Aurora Veil had been setup and Baxcalibur had picked up a few attack boosts (Either from Mismagius Mystical Fire or switching into fire moves meant for Abomasnow).
Essentially most games ended with Assault Vest Terra-Ground Baxcalibur spamming Earthquake with 1-2 attack boosts and 2x speed from Slush rush.
Obviously this is not an optimal team (Tailwind exists) but this was my first time playing doubles and it was very satisfying building this from complete scratch.
Other cool Parts of this team: Using Entrainment to override levitate so Earthquake could hit, also using it to speed up enemy mons in trick room (Happened less after I added Mismagius). Freezing Ghouldengo with Blizzard MULTIPLE TIMES Whatever this is
