Best Pokemon Mystery Dungeon. Zoroark - Master of Illusions. Heres my take on the best starters in Pokemon Mystery Dungeon DX.
Great for avoiding damage for all your Pokemon. This eliminates type immunity and makes resisted moves more powerful. Arceus and the Jewel of Life.
However there are a couple that we can kinda elevate above others.
Brave the mystery dungeons. This page explains which Pokemon are best to use each point in the story in the game Pokemon Mystery Dungeon. You can meet and recruit over 400 Pokémon in a dungeon-crawling adventure within their world. Also dual chop is one of the strongest moves in the game that is barely resisted by anything and gets high pp when leveled high.
