Feed best pokeblocks to your pokemon, Teach best moves for the contest your entering and just use the right moves at the right time.
There is no strongest pokemon. The best you can do is have a balanced team with a wide variety of moves. But it could be groudon. If you teach it solarbeam, and strong fire, rock, and earth moves. it will pwn.
use a good fighting type Pokemon like machoke and use its moves

You cant the only way to get groudon on sapphire is to trade it from ruby

Aggron and Rhydon are definitely the best Pokemon on Pokemon Ruby! Their big, strong and both are great and they're awesome!
20's and 30's are great moves.
