I think the more stuff we put out, the less this will be necessary and the less we'll even want to force matches like this (not every one has a clear "counter"). If you look at how the Marvel Wave One was set up, there's nothing like that at all. So even then it seems like more of a "Master Set" thing than a "Wave" thing.
That said, I'm sure some of this will naturally occur to an extent. Once Wonder Woman's out, someone's going to want to do a Cheetah. Once Thor's out, someone's going to want to do a Loki. And so on.
But the great thing about ala cart is that we work on what we're most interested in. If something's a priority for you, you have the power to control at least one unit that's coming out.
