Brendan's grid is pretty cool like all the Academy ones, what will be your move picks beside focusing on the rain weather and sync?
Thinking of Earthquake (enables trapping for multiplier), Liquidation and Offensive Studies.
But I am not entirely sure of Earthquake, he also gets Gobsmack 9 which allows you to invest in Growl, which debuffs very well Attack + random stat and also buffs team's sync, EQ is very spammable but Liquidation abuses rain, he certainly isn't a AS Cynthia copypasta EQ effects candidate here. So I guess I'll switch to Growl for general utility.

Will try to get Gladion because he's good and then daily rolls on Iris which has a very meh kit considering Melony's Frosmoth just came few weeks ago, not Ice Zone but still a great Ice support, it's annoying trying to get her just for a reliable points multiplier which is why this mode is so frustrating between RNG runs looking for Blue story and the insane ammount of yellow and red orbs needed for a good grid.
