This is not true. Sun is treated as an entity because all sun teams have something very important in common, Ninetales. For example some types of teams (weatherless) have troubles dealing with sun offense as it is. Imagine improving another sun playstyle to the point that they will have to account for it too. It will become almost impossible for weatherless teams to prepare against sun. Not sun offense or sun stall, but sun as a whole. It's the same concept as with the versatility of a single Pokemon really. It doesn't matter that sun teams can't be both offense and stall, what matters is that their versatility could make them very difficult to deal with and even possibly broken. This doesn't hold true here. The default for a Pokemon we are creating is to not have any move. We are selecting the moves that it should have based on competitive and flavor reasoning. If someone wants a move to be on Malaconda's movepool, however small the effect of that move will be, he must give some kind of reasoning, as if the move is useless (competitively and for flavor) the move shouldn't be in the CAP's movepool. If what you said was true, then every CAP we made would have generally good moves such as Spikes, and many other moves that wouldn't be bad on any Pokemon.
