Much like the Guild Store, the Guild Event Store rotates what shards are available every 6 hours. Also like the Guild Store, it's best to focus on 2 units at a time until they're both done, before investing Tokens elsewhere. Focusing like this will complete key squads faster, netting you better results in-game at a quicker pace.
Note: There are two units available in the Guild Event Store, Darth Malak and General Skywalker, that can only be purchased upon completing their Epic Confrontation events. When the time is appropriate to focus on those shards, if you have not completed the associated event, DO NOT skip forward. Hoard those tokens, because you will need nearly 70,000 to complete those characters.
