Pok�mon Heart Gold Team Help?

Its great so far... im thinking you should try bringing in some elements you have not used yet... For example steel or if you do have that element in one of the pokemons moves. You could get a pokemon for just that element. By this i mean... your pokemon so far dont have many of the element steel. Im thinking the 5th or 6th pokemon could be a pokemon to catch up too the elemental attacks that you missed. For example i mean something like smeargal (i dont know if i spelled right) because smeargal can learn every move. <
