the idea of this deck it to get galaxy eyes photon dragon out on the field as quick as possible. this can be achieved through the vast majority of effects use. Use reinforcement to add photon vanisher to hand to then special summon to add galaxy eyes to hand. Galaxy soldier can add galaxy expedition to hand also.
use 2 level 4 monsters to get starliege photon blast dragon to stop any effects targetting high attack monsters (Galaxy Eyes) also his special effect will allow you to summon galaxy eyes photon from hand
If you have galaxy eyes in hand then use the effects of the other cards to get afterglow dragon to hand special summon to then xyz summon number 62 prime then overlay into C62 upon entering battle phase activate the effect of C62 and send afterglow dragon to the graveyard to the then trigger its effect to summon a galaxy eyes photon dragon from deck to the field and doubling all XYZ monsters attack power giving C62 10,000+ attack
