Sending Junk to Other Side concept?

I noticed that the idea of sending junk tiles or pieces to an opponents puzzle field is not currently a concept page but I want to nail down the naming before I create it. Do folks have good or succinct names for this idea?

It would tie together Tetris Battle Gaiden, Super Puzzle Fighter 2, Money Puzzle Exchanger, Puyo Puyo Tetris, and other really popular puzzle games.

Or would "Puzzle Battle" be a better concept?

In Tetris, you "send garbage." So I'll throw "Sending Garbage" into the mix. Might be a disambiguation page: "Sending Garbage (Puzzle Games)" and "Sending Garbage (DK64 to Antarctica)."
