1. Maximize the number of types represented in your Pokemon pair's movesets. Shoot for a number as close to 8 as possible.
2. Try to cover your Pokemon's weaknesses while doing this.
3. Make use of the Wonder Mail codes for early access to otherwise hard-to-get TMs.
4. Above all, SPAM THE REVIVER SEEDS! Collect as many as you can, as this game WILL throw really cheap/unfair boss battles at you with fair regularity.
5*. Use a Powersaves device, if you have access to one, to give yourself a HUGE advantage (by starting at level 100 and 500 HP, as well as maxed-out gold reserves). As cheap as the AI tries to get, it can't do very much to you when you're at level 100 (as an early boss is "only" level 50).
