To build a team that stands out in the Bangladeshi scene, you need to prepare before registration opens. DotaBD enforces strict identity and eligibility requirements. Before a team can register for any league, all players must link their Steam account and verify their Discord account.

A registered team has structured roles: - Captain: Primary administrative lead. Can register the team, submit bKash payment receipts, add/remove players, and manage substitute lists. - Manager: Handles scheduling and coordination, sharing the captain's administrative permissions. - Player: Roster competitors.

The active core roster must consist of exactly 5 active core players marked as 'player', and up to 2 substitutes registered for match-day emergencies. During registration, the captain must declare the solo MMR for all core players. The registration call will fail if the declared MMR is missing for any core player, or if individual medals violate league boundaries. Furthermore, the Team Captain or Manager must have a valid phone number verified on their profile before registering the team, allowing organizers to easily reach out for scheduling updates.

Matches can be unpredictable, and player availability changes. DotaBD supports adding Substitutes to your active roster. When adding a sub, the system runs an automatic check. Instead of a static limit, the substitute MMR is capped dynamically based on the remaining team MMR headroom: $$\text{Sub MMR Limit} \le \text{Lowest Core MMR} + \text{Remaining Headroom}$$ where Remaining Headroom is the difference between the league's max team limit and the team's active core total MMR. This allows teams flexibility while preventing high-MMR smurfs from exploiting the bench.

Furthermore, the system audits all 5-player playing combinations of core and substitute players. If any combination exceeds the league's max limit, the team is flagged, and the sub is barred from playing in those combinations. Captains can also upload MMR screenshots to prove their players' rankings, which organizers manually verify. Finally, when registering, captains copy the official bKash number, send the fee, and upload the Transaction ID (TxID) and receipt proof to transition their status from pending to verified.
