Hi There. In 40 old father who started this game with my son. Need help playing

“Warrior Presents” 4 Pillars are a good guide (but slightly out of date now). See picture below and his video on YouTube.

Making it even simpler their are 3 main early goals:
1) Phoenix Team - the best early lightside team, can win GWar most days by themselves because they regen health/Protection. On days where you get a hard node —> you use your 2nd team (Empire) to assist.
Phoenix can unlock 2 Legendary characters - Thrawn and Emperor Palpatine.
2) Empire - Vader, TFP, Tarkin, RGuard + 1 Trooper/Boba Fett temporarily . Replace RG and the +1 with Thrawn and EP when you get them.
Empire - Unlock R2D2
3) Credit Heist Team - you need credits! Stick to BHs and Storm Trooper Han. You need BHs later on and you need STH for unlocking Commander Luke later on.
