So I know you have to watch Kingdom Hearts 358/2 days and do all the stuff in that game to get the Org. XIII enemy cards in ReCoM but I haven't gone through and done that yet. But I'm wondering if I need to finish Reverse/Rebirth mode and finish 358/2 days to get the cards. Do I?

I think you mean the new enemy cards. If so, you just need to watch the Kingdom Hearts 358/2 Days Cut scenes.

Finish Reverse/Rebirth then watch 358/2 Days scenes. And you should be able to get the special cards for Sora. Thats how it worked for me.

In order to get Org.XIII Enemy cards,you have to finish Sora and Riku's Story,and after that,you can get the enemy cards by finding the golden cards known as Rooms of Rewards I think.As for the bonus for watching Days cutscenes,you'll be able to get new Keyblade cards from Days by using bounty cards (the blue one...)...

I still haven't even finished Sora's story, but I got a Demyx card from Atlantica and I've watched 358/2. Never played as Riku on my 1.5. I did however watch the 1.5 credits, so maybe that counted as something somehow haha?

Well then, guess that answers it! Thanks!
