TSM|ZeRo started off his 2017 with a deep look at the entire cast of Super Smash Bros. for Wii U. The first video in the series dissects the four characters that land in the bottom tier, and he explains his reasoning for the choices.
ZeRo goes into detail about Jigglypuff and the many factors holding her back from being a competitive character. She has major weakness in terms of speed and range. With many good upper attacks in SSB4, the up-smashes can decimate the Pokémon with ease. Next, in spot 55 is the Mii Brawler. With the size restrictions in tournaments, the customizable character is held back in competitive environments. His stand-alone combos aren’t as good without those options. Mii Swordfighter has an edge over his swordless version thanks to a few good attacks. The range makes a significant difference. Mii Gunner has some good matchups against heavy and slow characters.
Listen to ZeRo work through each mentioned character in detail in his video below for some valuable insight into the current meta. The next one will tackle low-tier characters.
