I don't personally see a problem with them adding in the rest of the games' types as cards- just keeping the basic energy we have now. Where as ICE type would still require WATER energy but would have a different weakness and resistance than WATER type cards.
I realize that water and ice types DO already have different weaknesses in the card game, but I think the TCG really needs to get back into resistances and adding new card types could allow them to make a more fleshed out type chart- and would really add to strategy and less "Mono type" decks. You could run water type and ice type cards with the same energy requirements and tech in some electric or even fire types with a few energies for those.
I also think its non-sense that there are so many cards out now that have no resistance at all, when they should clearly have something. Resistances should be a staple with all types, not just types like steel and dark.
Bug types could use grass energy, but be resistant to grass type cards.
Ghost types could still use psychic type energy and resist psychic types.
Rock types would use fighting and resist fire etc. etc.
Another thing it would get rid of would be this psychic type card being weak to psychic type card crap.
If more types and resistances were available I believe it would add to the variety of strategy which could be used in deck building, as long as said new types still used existing energy like the Dragon type cards.
I agree with this strategy. I posted on the beach stating that they should add the Ice type, but still make it use water energy. After all, ice is solid water. The ice type card frame should be a lighter shade of blue, so that when you look from a distance, you couldn't tell water and ice types apart, but since they both use water energy, it doesn't matter, but if you look up close, you can tell that one is water, and one is ice.
Bugs use grass energy because they live in grassy areas, near plants, and represent the element of nature.
Rock, Fighting, and Ground represent the body and the earth, or the element of earth, and in any games, monsters with the earth element usually has high physical power, which is what fighting energy is. The energy of the mind.
Psychic and ghost types uses psychic energy because it is the energy of the mind. Usually you can't kill ghosts, in other games, with physical attacks, so you have to use magical attacks. Ghosts also have weak physical strength, hence the reason they use psychic energy, the energy of the mind.
Poison, I don't know. They feel more grassy, but they moved them to psychic because there were way too many cards that use grass energy back in the day.
Dragon I feel doesn't use dragon energy in the games. In other media, dragon breathes out fire, water, any element, but they never use all the elements. So what I am saying is, the dragon specializes in one element, but another dragon specializes in another element, and dragons as a whole group use a wide variety of elements. To make them distinguishable from conventional fire types and water types, they decided to make them use 2 elements at once. It fits the flavor perfectly, and they don't use dragon energy. None of the dragons in other fiction use "dragon" energy. They use fire, water, or lightning, or whatever, depending on the kind of dragon it is, and this is already represented on the existing dragon type cards we have.
I would remove metal energy and make them use lightning energy. We know electricity represents industrialization, and metal types represent urbanization, so the lightning energy represents the creation of cities and the destruction of forests. Their card frame could stay grey I guess, since changing them to greyish yellow would get people confused, but I don't really care for this change.
In place of the removed metal energy would be wind or air or flying energy for flying pokemon, who uses the element of air, but I can understand flying and normal types being colorless. Colorless means nothing special, and normal types represent nothing special. Air is also colorless, and nobody really takes notice of it compared to the earth, fire, and water. Air is only noticeable in tornadoes, hurricanes, and devastating disasters.
So we don't need Ice energy, Ghost energy, or Rock energy, or any more energy types, as the existing 8.
Grass = Nature
Fire = Fire element
Water = Water element, which ICE belongs to
Lightning = Light
Psychic = mind and mental strength
Fightning = physical strength, and physical objects like the earth
Darkness = evil, but I would rather have it represent darkness and the night, so maybe ghost types can use darkness energy instead
Metal = Industrializatoin and Urbanization.
This formula makes it so that each type has its opposite. Nature vs Industrialization. Fire vs Water. Light vs Dark. Body vs Mind.
If any of the 17 types uses one of these motifs, then a basic energy isn't needed for them. I already explained the how dragons use any of these motifs, but never all of them at once, but some uses 2 of these motifs, or any combination. Colorless doesn't use any of these motifs, so therefore, can use any basic energy they want.
