It has recently come to my attention that the genies and gen 4 mascots (this includes Ho-Oh and Lugia) you obtain via the Dream Radar only come in Dream Balls. Coupled with the fact these Pokemon are not catchable in Dream Balls otherwise, this means in wi-fi battles, a player can tell if the Tornadus/Thundurus/Landorus his or her opponent sends out came from the Dream Radar or not, and thus consequently whether it has its hidden ability or not (The gen 4 mascots are irrelevant since you know whether or not they have Pressure anyway). The reason I bring this up is that in wi-fi, players can tell immediately after Landorus is sent out if it has Sheer Force (Dream Ball) or Sand Force (not Dream Ball), and this takes away a lot of the surprise factor present with Landorus in simulator battles. I think that this may be the point at which it makes sense for the sim to implement Pokeball in some manner. I'm not sure what the best way would be, but it might be worthwhile to put a Pokeball icon to the left of the Pokemon's name (like what the game does with wild Pokemon when you've already caught the species). I wonder what the community thinks is the best course of action.
