"If you were to change one fundamental rule of the PTCG, what would it be?" I'm trying gather a few ideas for a little game development. It's a thought experiment more than anything, but I thought it would be fun to ask the question here more than anything. ♪ For me, I would think cards should have the ability to perform attacks without an energy requirement (and no, I'm not just talking about the 0 energy costs fromt he DP series). I remember when I was young, people I knew would pick up the cards and try to fight with them, but they just ignored the energy costs altogether. Even when I was older people told me they wanted to learn to play but they couldn't understand what the energy was for - there was no "energy" in the Pokemon games outside of "PP".
