What I found really interesting about the "leak" from yesterday was the mention of "dual-type moves", not the moves with two types used like most people think, but moves that are one type, but deal damage as another, similar to how psyshock uses the user's special attack and the target's defense.

In this thread, we discuss the possible effects these kinds of moves would have on the game, and come up with ideas for these kinds of moves.

tl;dr moves that use 2 different types for STAB and effectiveness.
