Alright, well, I'll do my best.
Starting off, I see it's a stage 1, which already makes it kinda bad. Stage 1 attackers are much more difficult to swarm. Then I see it's horrid 60 HP. I mean, really?! 60!? On a Stage 1?! Looking even further, it's got a fighting weakness to top it all off. Not sure how much worse this card can get until I read the attacks...
First attack is meh, discarding tools is cool but it's silly to run a crappy Stage 1 to do it instead of just using Tool Scrapper. Second attack is what makes Raticate interesting. For just 3 colorless energy, it brings a Pokemon down to 10 HP. This is MASSIVE against EX's and other high HP attackers, dealing up to 170 damage with one attack. It even goes through Eviolites!
The only way I could see this card being used is with Dusknoir to get massive damage onto the field, but the fact that it's a stage 1 with a less then sub-par HP just ruins it. I highly doubt this card will see any play due to it's faults completely outclassing the single benefit it has.
