A corruptive playstyle refers to a strategy in Super Smash Bros. 4 that was commonly utilized by Mario (and, by extension, Dr. Mario) in tournament matches. Corruptive playstyles are no longer relevant in Super Smash Bros. Ultimate, which introduced the learning switch.
In Super Smash Bros. 4, there was no Learn button, so Figure Players learned after each match regardless of whether their trainer wanted them to or not. Certain characters – specifically Mario – were trained to overuse side specials, grabs, and aerial attacks (which would lead to a poorly-trained FP). In a tournament setting, each match on the bracket consists of a best-of-three. In the first game, the Mario amiibo usually loses due to being purposefully trained poorly. In the second game, Mario’s opponent will have “absorbed” some or most of its poor training, while Mario will have inherited some of his opponent’s good habits. This often allowed the Mario amiibo to turn the tables and win the set by “corrupting” its opponent. Specifically, said opponent would be more likely to use short hop aerials, which the Mario amiibo could then perfect shield and punish with repeated up smash attacks.
This playstyle was rather common but unpopular; many trainers found it unfair that a poorly-trained FP could defeat a well-trained one simply by exploiting amiibo learning mechanics. In theory, a corruptive playstyle could still work in Super Smash Bros. Ultimate, but both FPs would need their learn button switched on. Almost all tournament-ready FPs in Ultimate have their learning off, and thus a corruptive playstyle does not work.
