A new “Fusion Arts” trademark has been filed by Pokemon. It’s under the same usage terms as the Pokemon TCG, meaning it could be an upcoming set or mechanic. In this case, it sounds more like a mechanic.
Trademarks are discovered five to six months in advance, so this would go into usage in the summer.
What do you think Fusion Arts will be? Maybe a spiritual successor to Pokemon LEGENDS, like Lugia LEGEND?
