When you release 5 of the same pokemon you get it's evolution in the form of a ticket until you redeem it.
Examples I Have:
5 Magnetons= Magnezone Ticket
5 Rhyhorns= Rhydon Ticket
5 Magikarps= Gyarados Ticket
5 Pikachu= Raichu Ticket
etc.

If you want the lake legendarys (Mesprit, Uxie, and Azelf) then in EX mode go to rocky cave and you MIGHT see Uxie. Then firey furnace for Azelf and Windy prarie for Mesprit. hope I helped!

Running low on money to buy moves and recruit pokemon?
Search no more! All you need to do to get lots of money is to find a lucky pokemon (when I say lucky I mean the Trait) and if your lucky you'll be able to teach it theif. When it knows theif if the final move you use to beat it is theif it will drop more money than usual! also if you are lucky enough to find a lucky pokemon it will drop even more money!

I was lucky enough to get a lucky Jynx so everytime I should get 1 I get 5. When I should get 10 I get fifty and when I should get 100 I get 500!!!

Happy Spending!

P.S This technique even works on bosses!

When you play a level and you see a Pokemon that has sparkles around it, leave it until last and it will either be a special trait Pokemon or you will have a greater chance of catching it.
