Blastoise 7 Star Raid using Walking Wake Build Pokemon Scarlet

Of course I did this raid off screen and was able to beat it the first time! Interestingly, that off screen raid everyone used special attack mons like Reshiram and Umbreon, while this raid everyone used physical attackers. Here's my build set for Walking Wake and the steps I took during this raid to beat Blastoise; good luck everyone and if you enjoyed make sure to leave a like and follow the channel!

Walking Wake:
Tera Water
Held Item Heat Rock
Sunny Day (1st turn unless another Sunny Day mon present, then after Blastoise uses Rain Dance)
Flamethrower (Turns 2-4; burn optional)
Hydro Steam (Turn 5 after Terastalizing until Sunny Day needed or PP runs out)
other move (Dragon Pulse was my fourth move but never used it)
