I think tiers are a load of bull. You shouldn't be afraid of using a certain Pokemon because it's in some imaginary "tier", you should use what you want, when you want. Tiers are a waste of time and solve nothing, they just make things more complicated when there's no need. If you agree, copy and paste this in your signiture (Started by Zero Nexus)
