I've fought a ton of Digimon without partners by now, and I've learned one thing they all have in common: They're all completely fucking stupid.

Rather than wishing for a miraculous victory, study. If your Digimon acts on instinct, even if it evolves, it's just a match of strength. But if you learn tactics, outsmart your enemies, even if it never changes form again, you'll stand a better chance.

I've got my notes and information here. I can't let them go yet, but you can come study them, and I imagine help me complete them. You can plan in advance for whatever may come.
