Editing Metagame

*{{SSB4|Meta Knight}}, obviously heavily nerfed from his dominance in ''Brawl'', was initially considered to be a shadow of his former self, and was generally considered unviable, with commonly given reasons being his short range and weak KOing ability (the latter of which is considered moot now). However, due largely to new strategies developed with him, most famously the optimization of his devastating up aerial combos, and along with significant patch buffs, he rose back up to prominence, currently placing high in the tier list, and while not nearly as dominant as in ''Brawl,'' he eventually earned his status as one of the best characters in the game. After receiving nerfs to his infamous up aerial in update [[1.1.5]], opinions on Meta Knight have begun to fall again, with him no longer being among the best characters in the community's view, though he is still regarded more highly than he was in the early metagame.  

*{{SSB4|Luigi}} was a very prominent character in low- and mid-level play, largely thanks to his effective projectile and his down throw, the latter of which led into highly damaging combos and guaranteed KO set-ups, and he was further aided by balance patches for a while. However, updates [[1.1.0]] and [[1.1.1]] nerfed him; the former patch increased the lag on his [[Fireball]]s, while the latter patch more importantly increased the knockback on his down throw, removing his KO set-ups, and the [[shield stun]] changes brought about by the same update hindered him due to his very poor [[traction]]. He went on to be ranked at 16th on the official tier list, in upper-mid tier, whereas he was considered a contender for top 10 prior to his nerfs. As of version 1.1.6 and the second official tier list, he is ranked 29th, but has risen to 18th on the fourth tier list.

*{{SSB4|Roy}} was a high tier and best sword-fighter in the eyes of many players (including {{Sm|ZeRo}}) at his release. This was largely because players would often draw comparisons between Roy and Marth, who was surrounded by a negative stigma at the time, along with the notable buffs Roy received to his mobility, damage output, and power in the transition from ''Melee.'' However, Roy has so far failed to attain notable results, and opinions on him have steadily dropped. With stronger performances from other sword-fighters like Meta Knight, Ike, and Marth himself, and with the inclusion of Cloud and {{SSB4|Corrin}}, Roy is perceived as a low-tier character, as is evident with his rank at 32nd on the tier list (which is generally considered too high), and to some, he is among the worst characters in the game, with the most commonly mentioned reasons being his unsafe attacks, limited combos, difficulty KOing, lackluster recovery, and vulnerability to combos. He has fallen to 50th place in the second tier list. He currently sits at 44th on the third tier list.

*Though initially viewed as a mid-tier, opinions on {{SSB4|Mewtwo}} plummeted not long after its release, with many eventually regarding it as one of the worst characters in the game. Such negative opinions were generated mainly by its unusual combination of very low [[weight]] and large hurtbox, which made it highly susceptible to both combos and early KO's, its lack of a reliable combo throw, and its generally worsened frame data coming from ''Melee,'' along with Mewtwo being adversely affected by the loss of advanced techniques like [[wavedashing]] and [[L-cancelling]]. However, in updates [[1.1.3]] and 1.1.5, Mewtwo received a plethora of buffs to its mobility, frame data, range, and damage output, as well as a slight increase to its weight. Furthermore, it would gain strong results from its mains, with {{Sm|Abadango}} going as far as to win [[Pound 2016]] using mostly Mewtwo. Mewtwo's placement at 37th in the low tier of the tier list was partly a result of its previously poor status, and this is widely thought to be outdated in light of recent results. As of now, many players view Mewtwo as a high-tier character, with some believing it to be a top-tier, and with a few considering it as one of the best characters in the game. In retrospective, some players say Mewtwo's once poorly regarded status was too harsh, and that it was underrated as a whole. These players were eventually successful in their argument, as it is now 10th on the tier list.
