Assist Trophies and Pokemon

I don't know if this has been suggested earlier in this thread, but the thought just popped up in my head, and to me seems like a valid and reasonable AT.

Tetris Blocks
Something in lines of several tetris blocks fall from the sky downwards and damage anyone they hit.

(And while posting this a quick stage idea came to mind, that I'll just mention briefly, since it's not really thought-out and I don't think it's worth making another post about: Tetris Stage: You are on a platform, and tetris blocks constantly fall from the sky, and landing on the platform as in the tetris game, and makes the platform higher and higher until a "line" is formed that clears that line, just like a tetris game, if you will, and it just goes on and on.)
