The set brings 120 new cards, including "Fusion Temporal", which allows combining the effects of two cards into a single turn, and "Space‑Time Anomaly", which forces players to reorganize their hands. One of the biggest highlights is the Wanderer character, who enters the battlefield with unique displacement abilities, able to change play order and create blocking opportunities. The expansion also expands support to up to five players, allowing the base game, which normally runs 2‑4, to be played with more participants without losing fluidity. The hand‑management mechanic remains strong, but now with more strategic discard options thanks to the "Inverted Time" cards. The 1‑vs‑many mode introduces the “Temporal Master” figure, who controls the card flow for the solo player, creating a constantly adapting challenge. Visibly, the expansion keeps the science‑fiction atmosphere of the original, with high‑quality components, futuristic graphics, and a soundtrack that reinforces the sense of temporal urgency. If you enjoyed Entropy and want an upgrade that expands replayability and tension, Echo of Time is the right choice to raise your table’s level. ## FAQ ### How many players does the expansion support?
