I HAVE MULLED OVER THIS QUESTION FOR SO LONG. my answer is situational because i’d like to raise teams that work well depending on team goals and needed coverage.

i’ll list the team that i’m working on right now for pokémon platinum, since it would be very close to my normal team for exploration:
infernape, blissey, togekiss, gastrodon/quagsire, froslass, and electivire. (no trades so i will be using luxray or jolteon for my actual playthrough. but yes, electivire.)

honorable mentions include: decidueye, alolan raichu, swampert, walrein, garchomp, vespiquen, and gallade.
