you can grind SS Gokus from the Transcended warrior event... and they are at SSR already so its a decent chance they will raise SA on most gokus

you will be able to farm SS3 goku (Angels) once we get the rebirth on epic showdown goku - also, based on your box, the following have farmable SA

Fusion Zamasu - stage 1 of eternal god

piccolo - from his strike event

whis - level 19 hero extermination

frieza (final form or 1st form) - from evil emporer... dokkan to farm final form

cooler - from the strongest rivals - dokkan to farm

im sure you've got more than the 31 cards in your box though - if you update i'll let you know what can be farmed
