Circuit Breaker

Circuit Breaker Set

On 29 September 2026, shortly after the announcement of the Dalek Invasion Set, Master Replicas released a Limited Edition collection based on the Doctor Who spin-off series Circuit Breaker.

The Circuit Breaker Set was limited to 750 units worldwide and contains 15 cards. As with the Doctor Sets, each set contains a complete, predetermined selection of cards rather than randomly distributed cards. The cards feature a silver foil finish.

Unlike the Doctor Sets, which use their own numbering sequences, the Circuit Breaker cards continue the numbering used by the 2026 Battles in Time collection. The 15 cards are numbered 143–157, placing the set after the Obliterator collection and before the Dalek Invasion Set.

The set also includes a Vortex card as an additional card, following the format established by the Doctor Sets. At the time of writing, the identity and specification of the Circuit Breaker Vortex card have not been confirmed. It has been suggested by collectors that the card may feature the Fugitive Doctor; however, this remains unconfirmed and should not be treated as part of the established checklist until further information is available.
