Colorful Wind This attack does 30 more damage for each different type of basic Energy attached to this Pokmon
By Type Identify cards by The basic Pokmon types are: bug, dark, dragon, electric, fairy, fighting, fire, flying, ghost, grass, ground, ice, poison, psychic, rock, steel, and water
One example is the Davros card, which will not only make your opponents lose three life points on your next turn, but they also have the choice to either discard a card themselves or allow you to choose one
The eyes are chefs kiss though
And remember that you can copy instants or sorceries even if they don't have targets (you just don't choose any target in that case, of course)
In an artifact-focused build, you can pair it with draw engines like Thought Monitor or cost reducers like Etherium Sculptor to snowball quickly into overwhelming board presence
