I was actually about to write a review on this:
LOST REMOVER WAS THE HERO OF MY REGIONALS!!
I was playing a magnezone disruption deck. The primary idea is to use gyro ball to make opponent switch, then lock their trainers with a spiritomb afterwards. Plus I play a judge as much as I can to kill their hand, and keep mine going with magnetic draw. So the night before regionals I was flipping through my cards looking for another kind of disruption to throw in. And I stumbled across lost remover. So I figured, what the heck I'll trow in a couple.
Originally my thought was I'd be lost zoning double colorless attached to tyranitar, steelix and the like. Most of the deck I played against were Machamp and gengar, though. Both of which run rescue energy as their primary recovery. So guess what. No recovery. I won 2 of my 8 games entirely because of lost remover. The first was because I killed the rescue energy and then the machamp, which meant they didn't have another one out, and the second, because I killed the rescue on a gengar, and they didn't have enough energy to cursed droplets. I also lost removered some special darks, but not to much concequence.
My conclusion: Lost remover is under valued, under appreciated, and under used. I shouldn't be left out of any deck intended for disruption.
My rating: 5/5
