Not at all. By the way the game works now, the text "this card counts as basic energy" isn't even necessary. All Special Energy is marked as such with the text "Special Energy". Just omit it, and it is basic energy. There is no rule stating that basic energy can't have any special rules attached to it.
I'm not 100% sure about your claim
but I'm pressed for time at the moment; so
assuming you are right it still takes a simple concept (doesn't have to be a hard and fast rule) and makes it more complex.
Here's the problem:Magic tries to force you into building with 2+ colors because a single colors have obvious weaknesses. In Pokemon, it doesn't happen that way. More-so, running 14 energy is a very high amount (it is usually closer to 10), but to be competitive in MTG, you have to play around 20 in a typical Standard deck.
I am not very knowledgeable of M:tG, but I'm not kidding:
Haymaker, one of the
earliest dominant archetypes, a deck birthed in the original
Base Set, managed to include two non-Colorless-Type attackers in the same deck:
Electabuzz and
Hitmonchan.
Yes, neither of them needed two Energy, but fast-forward to the BW-era when
Rayquaza-EX (DRX) managed to do just fine with
Elektrik (NVI) and
two basic Energies even though
only one was affected by the latter's Ability.
With respect to
both of these points, it still does not justify a basic
Dragon Energy card, merely a reperint of
Double Dragon Energy or other shortcuts. We've had Dragon-Types requiring multiple Energy-Type for a few years prior to the release of
Double Dragon Energy, and we had some top decks use Dragon-Types during that time. At best you can present this as a
possible path, but I do not believe it to be a wise one.
