Those card outlines make this specifically a Yugioh mat

It’s because there are two shots in the sequence, but one of the shots (the one of Timmy) has an abrupt slide midway that seems continuous while looking at it but seems like discrete shots when in your periphery.

Looking away makes it feel like you went from “dot-dash” to “dot-dot-dot” so the whole thing suddenly seems to speed up.
