Compare the Underwater Cities and Trickerion promo realms for Rolling Realms. Both add six cards and need the core game, so choose by theme and table fit.
Quick answer
Choose the Underwater Cities promo realm if your group prefers a marine, city-building theme; choose Trickerion if you want a theatrical, magic-inspired theme. Both are six-card promo packs that require the Rolling Realms core game, so your decision comes down to which theme your table will actually play.
The only real difference is theme
The supplied catalog facts for both promo packs are nearly identical: each expands Rolling Realms with six promo cards inspired by its source game, and each requires the Rolling Realms core game. No card mechanics, player counts, or play-time differences are listed, so you cannot use this comparison to choose based on gameplay depth. Treat the theme as the deciding factor.
Price and value are close, but not identical
The Underwater Cities pack is listed at USD 3.40 against a USD 5.00 comparison price, while the Trickerion pack is USD 3.65 against the same USD 5.00 comparison. That 25-cent gap is small, but it means Underwater Cities is the slightly cheaper add-on if you are buying only one. Neither pack includes the core game, so budget for that separately if you are new to Rolling Realms.
When to buy both instead of choosing
Because each pack adds six cards and the packs are inexpensive, buying both is a reasonable option if your group already plays Rolling Realms regularly and enjoys swapping in different realms. The trade-off is shelf space and the chance that one theme goes unplayed. If your group is new to the game, start with one pack and add the other later.
Trade-offs at a glance
- Theme fit: Pick Underwater Cities for a marine, city-building theme or Trickerion for a theatrical magic theme. The catalog lists no mechanical differences, so choose the theme your group will enjoy seeing on the table.
- Price: Underwater Cities is USD 3.40 and Trickerion is USD 3.65, both against a USD 5.00 comparison price. The difference is minor, but Underwater Cities is the cheaper single add-on. If you are buying just one and are indifferent to theme, the lower price favors Underwater Cities.
- Core game requirement: Both packs require the Rolling Realms core game. Do not buy either promo as a standalone game; check that you own the core set first.
