Doctor Who: Battles in Time came back in 2026 with two very different sets carrying the relaunch, and collectors jumping in now need to know they are not the same kind of product.
Retroduction arrived first, built around the 20th anniversary of the original 2006 card game, while Obliterator followed as the first set made entirely of new material.
One leans hard on nostalgia, the other is a clean break into new checklist territory, and knowing the difference changes how you should actually shop for either one.
Here is a direct, card-by-card comparison of what each set contains and which one fits your specific collecting goals.
Retroduction is an 80-card Game Pack built as a 20th-anniversary tribute, with 72 of those cards being foil reprints pulled directly from the five original 2006 through 2009 series: Exterminator, Annihilator, Invader, Ultimate Monsters, and Devastator.
The remaining 8 cards are brand new, featuring the Fifteenth Doctor, his closest companions, and some of his most dangerous foes, giving longtime collectors a small taste of new material inside an otherwise nostalgia-driven set.
Obliterator takes the opposite approach entirely, with all 142 cards on its checklist being new artwork, spanning every Doctor from the First through the Fifteenth with no reprinted material anywhere in the set.
Where Retroduction is designed to look backward, Obliterator is designed to establish the revived game's own visual identity going forward, which makes the two sets complementary rather than competing.
Retroduction was originally slated for a March 2026 release before shipping actually landed in the last week of April 2026, putting it first out of the gate for the relaunch.
Obliterator followed later in the year, releasing in the UK across August and September before reaching North America on October 15, 2026, making it the set most new collectors will actually encounter first.
A reprinted Exterminator-series card inside Retroduction is still the same artwork long-time collectors may already own from 2006 through 2008, just with a fresh foil treatment and a new 2026 print run behind it.
That matters for value: an original-run card and its Retroduction reprint are not interchangeable collectibles, even when the artwork looks identical at a glance, so track which print year you are actually holding.
A collector trying to assemble the full five-series original run from 2006 through 2009 gets a meaningful head start from Retroduction's 72 reprints, even if the originals themselves stay the real long-term target.
A collector who only cares about the revived game going forward has less reason to chase Retroduction specifically, since Obliterator's all-new 142-card checklist is where the actual new chase cards live.
Keeping Retroduction's reprints separate from Obliterator's new cards in dedicated binder pages makes it far easier to track which era each card actually belongs to as the checklist grows.
That separation becomes more important as additional 2026 sets release, since a mixed binder gets harder to audit the more sets get added to a single collection.
Many collectors jumping into the 2026 relaunch end up ordering both sets together, treating Retroduction as the anniversary tribute piece and Obliterator as the set that actually grows the collection going forward.
That combined approach costs more upfront than picking just one set, but it avoids the regret of skipping either the nostalgia angle or the new-material angle entirely.
Retroduction's Game Pack format tends to carry a lower individual price point than a full Obliterator booster box, reflecting its smaller 80-card scope compared to Obliterator's 142-card checklist.
That price gap makes Retroduction a reasonable entry point for a budget-conscious collector who still wants a taste of both the classic reprints and the new Fifteenth Doctor-era cards.
Battles in Time's 2026 calendar already spans more than two sets, and Retroduction's reprint-heavy approach means some cards will look deceptively familiar next to their 2006 through 2008 originals.
Keeping a simple written log of which print year each card belongs to saves real confusion later, especially once a third or fourth set enters the same collection.
80 cards total.
72 reprints and 8 brand-new Fifteenth Doctor-era cards.
Exterminator, Annihilator, Invader, Ultimate Monsters, and Devastator.
No, Obliterator's 142 cards are entirely new artwork with no overlap.
Retroduction rewards nostalgia and completionist instincts, while Obliterator rewards collectors who want to build a stake in the relaunched game's own new material.
Whichever set you prioritize, sort the two eras into a zip-up 9-pocket binder early so reprints and new cards never get mixed together by accident.
