How I dealt with 425:
Spoiler
I used a Namine Metal to copy her damage boost/defense boost, then used my Minnie Mouse to heal when my HP got low. Stacking on a ton of defense boosts helps too.
I've also thrown a bunch of money at this game, so I dunno how hard it would be for a F2P user.
Anyway, I just used someone elses Minnie in the party to heal. Any healing metal should work. Namine is such an OP metal x.x

Yeah, with my luck, I'll never get Namine. I can't even get a magic Leon. I've got Minnie, Daisy, and Tinkerbelle for healing, but even they're not enough to help me get past Master Ava. I don't think the game is that much harder for a F2P player as you're still relying on luck to get good medals whether you're paying or not.
I'll see about trying to get more defense boost Scrooges, but I haven't really come across much in the events.
