Yep, IMO Trapinch is a relatively low-rankin' 'mon for in-game tier lists. It's Attack is overkill early on, but by mid-game it becomes somewhat underwhelming... mainly 'cause of it's other awful stats and sub-par movepool (unless ya breed EQ onto it). Vibrava's only strength is it's typing since it's Attack actually decreases, and while Flygon is decent, it isn't all-that great since Trapinch 'n Flygon have the same base Attack (Game Freak really ****ed up on that one). 'Specially since a level 45 evolution is quite late. Not too late for a Single Challenge, but still problematically so.
