The trick will NOT work. You NEED Wailord in the last slot of your party pokemon.

To get Wailord fish. To get Relicanth, dive underwater and search. -Catsura
Because you need Earthquake on Relicanth and Surf, Dive and Waterfall on Wailord. You need Relicanth and Wailord in your party to catch the Regi Pokemon as they are the Pokemon which can unlock all the chambers around Hoenn. The underwater cavern which allows you to unlock every Regi chamber requests that you have a Relicanth and a Wailord in your party. These Pokemon and no others serve as a key. Their pressence fulfills the caverns request and the chambers are unlocked. Relicanth and Wailord also serve as useful Pokemon as between them, they can learn most of the HM moves required to encounter the individual Regi Pokemon. However, they are only necessary for the underground cavern.
Wailord does not currently evolve into any pokemon, but it does have the pre-evolution wailmer.
Not sure what you are saying but in platinum Regigias can be found in snowpoint temple but must bring regis from emerald where in emerald you can find the regis in seafloor cavern if i am correct and must crack a code with wailord and another Pokemon and another Pokemon i don't remember.
No, but a 45 wailmer is basically a wailord.
you can find it at rout 129
in shinetown city
You do not need a Wailord to catch a Registeel in Pokemon Emerald. You may need a Wailord or any other water-type Pokemon to surf to the place where you catch Registeel, but other than that, you don't need a Wailord.
wailord you have to evole from wailmer and relican you find in dive mode.

Evolve a Wailmer (Level 40)
Get a Wailmer and evolve it. It evolves into Wailord at level 45.
Wailord do not evolve any futher. They are the first and last evolution of Wailmer, who evolve into a Wailord on level 40.
You need Relicanth to be first in your party, and A wailord as the last, and then when you've read the braille you need to get one of your Pokemon to learn dig.
You Can't
Swampert or Wailord.
