Beast type

[rglezg]

As pointed in #24, I propose adding a new Beast type. This discussion is for explaining the concept and define its effectiveness and moves.

Concept

Not much to say here as I think the "Beast" name is self-descriptive. The type concept is about fury, instinct and wildness.

Effectiveness

Strong against: Beast, Fighting, Dark
Weak against: Dragon, Poison, Beast
Not very effective against: Steel, Grass, Rock
Resistant to: Ice, Fighting, Dark
Does not affect: Ghost

Proposed moves

Horn Attack	Normal
Fury Attack	Normal
Fury Swipes	Normal
Rage	Normal
Belly Drum	Normal
Roar	Normal
Trash	Normal
Horn Drill	Normal
Take Down	Normal
Stomp	Normal
