Tiers are usually used when categorizing advanced tactics and such.
This isn't the case, the little things are what often win the battles.
Move speed, drop rate, hit boxes, run speed, weight, and recovers all play a part in tiers.
Meta Knight is top tier because of transcended priority, the "priority" being that he can hit you through almost any move, even if you're mashing the forget outa buttons.
Luigi, Olimar, DDD, Peach and Diddy all have some form of transcended priority.
Ice climbers is way up there because of "waddling" the ability to De-sync your second person and chain grab/spike the opponent off at 29%.
DDD has so much weight it would take at least a smash from Captain falcon to send him off even at 150% HP.
Meta knight has his downsides, but that is ignored because of his amazing priority.
Tiercigarettes are literally the best Smash Brothers fans *Fixed*
Before this I was a richard who didn't even know about the game, I actually put time in to this and now I'm 2nd regional in Arkansas.
So before you call someone a "Tier cigarette" make sure you know the actual benefits of being one.
