Wave 4 wasn't that bad for me in the end. Even if it is one that had some of the most I wanted. Sure, I wasn't able to pre-order, but it wasn't the end of the world and I was fine with it.
I still got Jigglypuff & Inkling Boy on launch by just walking in and buying them.
Got a Charizard a couple weeks later in a store fairly easy.
Then found Robin, Lucina, and Greninja later on online at decent prices from imports.
Inkling Girl was the most recent, found at GameStop same day Mewtwo came out.

Once in my dreams, I rose and soared. No matter how I'm knocked around or beaten down, I will stand up restored.
