Phew catched 10 monsters each from Thunder Plains and Calm Lands and from items gotten I gave every Aeon Doublecast + made awesome Auto-Haste/Shell/Protect armor for Tidus that's definitely help with more catching.

Plus I stole like mad things like Poison Fangs, Dream Powders n stuff for further catching. It's actually pretty hard when you aren't escaping from any battle and aren't using sphere grid. Stuff gonna take weeks. My play time is already around 45 hours and it's gonna get much higher ._.
