Can I create a TCG with "energy" attack-based creatures without getting sued by Pokémon?
I'm currently working on a TCG, and give or take, we have most of the set rules, mechanics, synergies, math, deck building rules, special card ability limitations and card placements down. (I say lightly as we haven't play tested yet and are seeing the cards from different pre-built decks point of views and not completely yet from randomized deck building).
This project once finished most likely won't expand into other "sets" since it's mainly a promotional product for an album I plan on releasing, as well as focused on the world already built around my persona and from comic books and other things. Making it more of a single set TCG.
The play style is very different from other TCG games, while of course it also grabs elements from several games, my main concern is that one of the fundamental concepts of the game is that creatures use abilities and attacks powered by "energy" cards as well as supporters. Would I get in trouble at all for using those concepts in my game for commercial use?
A bit of detail of how the cards work and differ from Pokémon
Energy cards are labeled different musical notes. Some creatures may be able to use their abilities and attacks with any energy musical note card, and some need specific chords or keys to attack or go roam (go to the bench).
Energy cards are drawn from a deck which is similar to Pokémon. Or can be searched for when a certain moon card is in phase.
Supporters, in comparison to Pokémon's function, they stay on the player's field. Each player can have up to two supporters at a time functioning as both a single target unit while also as either; draw engines, kingdom ability boosters, creature enhancements or moon, land or world utility controllers.
