With that being said, if a Pokémon requires a TM found in a detour off the main path (like TM24 Thunderbolt on Route 18 with Surf or TM47 Low Sweep in lower Wellspring Cave with Surf), it will be knocked down a bit. What moves does the Pokémon naturally get and can possibly obtain? Unlike with past games, TMs are of infinite use and thus have no opportunity cost.

Does it require significant backtracking, require HM moves, or just have a low encounter rate? This includes backtracking to revive the Plume Fossil or Cover Fossil in Nacrene City after obtaining one in the Relic Castle, as well as catching Water-types, Cobalion, or Virizion post-Surf. Availability: This is how early a Pokémon becomes available in the game and how hard it is to find (read: encounter rate).Pokémon are ranked under the following five factors: Pokémon in higher ranks, such as S and A, are considered very efficient, while those in lower tiers, such as D and E, are considered not very efficient. The major factor under which each is ranked is efficiency a Pokémon that is efficient provides faster and easier solutions to major battles, which include Gym Leaders, Elite Four members, and N and Ghetsis at the Pokémon League, than ones that are inefficient. Welcome to the Pokémon Black and White in-game tier list! The goal of this list is to rank every Pokémon in Unova in one of the six tiers, from S to E, each vaguely determining its viability.
