In Gateway Colleseum's Trade Battle, there are different pokemon you can trade in different ranks. In the Pokemon Battle Revolution strategy guide, however, it lists the pokemon that appear in each rank. So I think, "How about I use this information to make a PBR Tier List?) So, Here is a list of PBR tiers for trade battle!

*Basitodon is a Rank 3 in Double Battles and Rank 5 in Single Battles. Since it can appear in Rank 4 anytime, it is under Rank 4.
**Pikachu is Rank 7 in Trade Battle. Since it is obviously nerfed, it doesn't count. It would make more sennse in Rank 2.
***Ranks 0 and ? don't appear in Trade Battle.
