Is it safe to assume I'm supposed to send Pokémon over from the GBA games to have any chance of clearing the Orre Colosseum (this is in OG Colosseum, not Gale of Darkness)?
Even if I did grind up to Lv100 to complete the Tower Colosseum modes to unlock the Orre ones, I don't think Colosseum's in-game roster is good enough to beat all the legendary spam, especially not when I have to face stuff like pic related in single battles after playing an entire game geared towards doubles.
