First to get, Throh is pretty good to have on backup. Mostly second-move fighting type, dishes out tons of damage.
Darumaka is an op little thing. If you don't have it as your main fire type (if you didn't choose fire originally) you're gonna have a problem.
Sigilyph is the last necessity for you. It's psychic and can fly, so you won't need that week starter bird in the starting area. I finally chose to get this beast after npcs with it tore through my team time after time.
And, don't use any of the pansear/pansage/whatever the other one is in your main team. they're not good enough.
sorry for being late, power supply failed yesterday.
