Stale-move negation

Stale-Move Negation is an event that happens whenever someone attacks in Super Smash Flash 2, as well as every other Super Smash Bros. game. It was added in v0.6. Whenever you attack, the move (Up special, Down smash, etc.) the player used is put into an invisible list which records the last 10 attacks that you have used. The more times a certain attack appears on the list, the weaker it will be. This means that if you spam a single attack over and over again, it will become weaker and weaker. Even a fully-charged forward smash against a foe with about 50% can hardly do any damage and do little knockback when it is fully-decayed (on the list all 10 times). This is why it's important to use a variety of moves. The attack has to connect in order to appear on the list and become stale. If the attack is not used after nine other attacks are used it will become fresh again.
