Though Figure Players have been well-supported throughout the Super Smash Bros. series, it has become clear that the developers never intended for a metagame to be formed around them. As a result, there are many aspects of amiibo play that are considered overpowered or broken; these include characters, stages, and equipment and Spirit effects. Several of these elements have been banned, but others are permitted, albeit under a set of restrictions.
Several characters and equipment items were banned in Super Smash Bros. 4. The Critical-hit capability and Explosive perfect shield bonus effects are entirely disallowed and cannot be used with any compromise. Little Mac and Cloud were once completely banned, but are now permitted with certain restrictions on their equipment setups.
With a maximized Attack stat, Little Mac can used a forward smash to shatter a full shield in one hit. Smash 4’s defensive AI had no response to this “technique”, which soon cemented Little Mac’s status as the best character in the game. The entire cast – save for Bowser and Rosalina & Luma, who went even – was hard countered by Little Mac. He was banned from competitive play for several years, but was later allowed under specific conditions: his Attack stat must be zero or less and he cannot utilize any Attack-boosting bonus effects. Cloud was nearly banned for the same reason; a maxed out forward smash could shatter a full shield. He is now permitted in tournament play so long as his Attack stat is +60 or less.
In Super Smash Bros. Ultimate, Bowser and Incineroar are both completely banned from the Exion amiibo metagame. More information can be found in these two posts. In the first few weeks following Ultimate’s release, Olimar’s Pikmin disproportionately scaled applied Spirits, causing several of his attacks to become one-hit KOs. This unintended behavior was later patched and the ban on Olimar was lifted. In terms of Spirit effects, Super Armor, Slow Super Armor, Great Autoheal, Autoheal, and Armor Knight are generally banned from Spirits tournaments due to their extreme overcentralization.
In recent months, trainers have begun unofficially “banning” S and A+ tier characters (as per the amiibo tier list) from tournaments to encourage experimentation with a wider variety of fighters. As a result of this trend, Wario, Ken, and Shulk (among many others) have received additional representation.
