Eelektross is actually pretty damn good for an in game team. While it's defenses aren't amazingly high, nor is it's speed, the fact that it has no natural weakness outside of uncommon situations such as Smack Down, Gravity, or Mold Breaker, means it can take a few more hits than most other Electric types. Not to mention it's massive attacking stats with a fun and varied movepool. So in short, it'll do very well. Just be warned that Tynamo is.........let's just say he's a lot like Magikarp....
