Let's say about a "demake" of Artifact (Valve's card game).
The new game would be a "generic" Artifact that doesn't use the lore, characters, and other protected things, but uses the same concepts
The new game would have the same exact amount/number of cards from Artifact, but all cards would be renamed (these cards would also retain their mechanics and abilities). The game would also retain the gameplay style (players competing into three separate boards) and UI layout (with a few changes).
Would this infringe on Valve's IP (in this case)?
