The 3+ SSR line is what makes this a starter you can actually play rather than a pull simulator. Three SSRs is enough to cover Burst I, Burst II and Burst III in a single squad, so Full Burst chains are online from day one without borrowing units through the friend system. The Gems double as Synchro Device slots, spare bodies for Limit Break, and shop refreshes — the account keeps climbing in Tribe Tower and Solo/Union Raid long after the banner pulls are spent.
