>>54450319>Level 1 (Zero Island and DT)Drifblim, Drifloon, Smoochum, Spiritomb and Rotom are the game's ezmode. Drifblim specifically is popular as a /pmdg/ pick for Unburden and Minimize being so mindlessly easy.
>recruitingTry to recruit on even floors for female Pokemon when possible. Female mons in PMD are innately better for having more accuracy and evasion than male mons. For prep on a recruiter, hypermax a mon you like and a mon in IQ Group B with gummis and seeds for an easier time, the latter mon being required to get Kecleon and also making things easier through Nature Gifter IQ skill, letting it raise a whole party's worth of mons with seed HP/level buffs.
>good team members outside of Lv1For the most part, the game is free so you don't need to give a shit. If you're really tryharding though, consider Smeargle for moveset versatility (moves like Haze to clear heavy debuffs like Memento on the fly, Refresh to cure status instantly like Perish Song instakills, and general multihits and ranged moves), Rayquaza (Sky Gem makes Flying types move at double speed, combined with Air Lock always leaving weather at neutral, he'll always be faster), or the above mentioned Lv1 mons, alongside an invested IQ G mon as a party member (full map view and stair pointer)
