To easily catch the Pokemon that show up in different seasons, instead of waiting for the season to change, simply change the system date under the DS settings to the desired month of the season you want it to be. Then, go to any zone, and it will be the corresponding season you changed the date to. You can now catch the different seasonal Pokemon and gain the seasonal items. -From: Kojihidari
Drop off any desired Pokemon at the Day Care Center on Route 3. For each step you take, your Pokemon in the Day Care Center will gain 1 experience point. Run back and forth on the Skyarrow Bridge twenty or more times, and your Pokemon should level-up a few levels by the time you are done. Repeat this process for any desired Pokemon. Note: Make sure you have a lot of money, as you must pay 100 coins each time your Pokemon levels-up.

The wings that appear are: Health Wing - HP, Muscle Wing - Attack, Resist Wing - Defense, Genius Wing - Special Attack, Clever Wing - Special Defense, Swift Wing - Speed, Pretty Wing - no effect; its only purpose is to be sold. Note: All wings except the Pretty Wing will raise the base stats until they reach 255. -From: jjsandt
When you encounter a Pokemon you want to catch, weaken it in whatever way desired (HP reduction, status infliction, etc.), then throw an ordinary Poke Ball. When the view zooms in on the Pokemon, use your stylus to trace counter-clockwise circles around the Poke Ball symbol on the touch screen. While doing so, make sure to not trace your circles too fast or too slow. Try to find a good median speed to trace with. This should either make the contained Pokemon roll more or get captured in one roll. Note: This trick seems to work best on higher level Pokemon (at least high level 30s), but it does not work every time you try to catch a Pokemon; it can simply make captures easier with ordinary Poke Balls.
Set the system date to your birthday. Then, go to the Pokemon Musical, and talk to the owner upstairs to get the birthday cake prop. Next, talk to the nurse at a Pokemon Center, and she will ask if it is your birthday. Answer "Yes", and she will wish you a happy birthday. Additionally, the mist will be gone in Routes 14 and 15.
