I need you guys to tell me some trainer cards that could be good with strategizing in decks.

Am I supposed to tell you something now or was this just to get a comment?

These work in any deck unless specified otherwise:

Items: Nest Ball, Ultra Ball, Buddy-Buddy Poffin (coming in Temporal Forces), Rare Candy (sometimes), Switch (most times)

Supporters: Iono, Professor’s Research, Boss’s Orders

Stadiums: Artazon (almost all the time)
