It’s long been my understanding that when you send a team-up to a teammate, the game selects one of that character’s powers at random. (This is also what it says in the nice-but-sorely-out-of-date “On Patrol” guide in the Tips & Guides subforum.) So, for example, if you want to send whales to somebody, you have a 50/50 chance of that player actually receiving A Little Off the Top. (Unless you roster a 1-purple version.)
I got the idea in my head that 3* Carol’s red power (Photonic Blasts) would be a nice way to deal with irritating Kitty/Bill matches, since it wipes out all protect tiles in one go. So I requested 3* Carol team-ups from my alliance. I then proceeded to get 10 straight of her black power (Hypersonic Punch). I decided that, for some reason, her red just must not send.
But then an alliance mate got the idea that most people probably had her powers set at 3/5/5 – or, the red at 3. So he readjusted her covers to put red at 5 and whaddayaknow? Her red power was sent.
After some experimenting, I believe I can confirm that adjusting the cover distribution does, in fact, impact what power is sent – certainly a compelling reason to set your Deadpool at 4/5/4.
So my question is this: Have I been behind the curve on this information, or is this a recent change that isn’t widely known?
