Help finding an upcoming grid-based TCG

Within the last 6 months I found out about a not-yet-released fantasy-themed TCG (maybe it was an ECG?) that focuses on 1v1 dueling using a single character card with additional weapons and abilities. There is grid-based movement on a printed playmat that looked like a castle dungeon kind of environment.

Does this sound familiar to anyone else? Google, reddit, and personal history searching has totally failed me.
