People with grass decks have a few options in the way of beating steel pokemon.
 
1. Use Yanma
   
Yanma is a neo discovery card with swift(if any one doesn't know what swift does, it ignores resistance) which is almost a must if you plan on killing steel pokemon with only grass.
 
2. add fire to your deck
 
This seems to be the most obvious solution but not always the best.  While you add fire cards to stop steel, you're using space that could be used to enhance your grass pokemon.  In english, it's a drain on resources.
 
3. Use Unown M
 
Unown M's pokemon power is another good idea, but too many in a deck becomes more of a waste than a solution.  It evens the playing field rather than giving you a distinct advantage.
 
Well, there you have it.  I wish all of those Grass players luck getting rid of those pesky steel pokemon.
