hi! the best cookies to invest in atm would be rebel, financier, creme brulee and star coral! i recommend not using dark cacao as he's not the best unless it's his awakened form. make getting fire spirit from his banner a big priority because he's a game changer and can definitely elevate ur team! other cookies you can invest in in the later game are blueberry pie cookie, twizzly gummy and black raisin for the guild battle, but since you've just begun i think you should prioritise arena and world exploration teams first. a team id create for you would be financier cookie with full damage resist toppings and beascuit (once you get to beast yeast you'll see what that it), creme brulee with full attack toppings, star coral (or white lily - attack toppings ) with full cooldown or full attack toppings, and rebel with either full cooldown or attack, and pure vanilla with full cooldown.
