Kingdom Hearts II Help! Repliku II

I'm finding it terribly hard to beat Repliku II. He card breaks me a LOT now and is extremely fast. I don't have enough Zero cards and don't know where to get them. The Moogle Shop room helped for the previous battle, but not that much for this one.

At the moment, I'm in Atlantica and am constantly trying to Level Up so that I can get my CP increased, but it's very difficult seeing as I've already Leveled Up a lot in this world thus causing my required EXP to be of a much higher amount.

My deck is, as of now, conceived of ONLY attack cards and healing items, besides two Cure cards of 6 and 3. I have another Cure card of 1 but that's too low and is a waste of CP. It's VERY hard to get Cure cards, and Cure cards of a good amount too, and so I'm stuck.

Please help? What's an easy way to beat him? I know I might have problems in the future, but I've been stuck on this for a few days now T.T~

 

Even on Proud Mode, this seemed to work on almost all the bosses I encountered... it's kinda cheap, and it worked for me, so maybe it'll work for you.

Set up your deck with consecutive Sonic Raids and quite simply, spam them over and over again. I find that the timing of the knockback and Sora's follow up are so in sync that the enemy is unable to use their cards to break you. This actually worked for so many Organization Members and Riku Replica it's actually ridiculous how Proud Mode let that slide.

I'm assuming this is Re:CoM since it's in the Final Mix+ subforum. If it is, I can assure you it's worked for me on Proud Mode. <.<

Have a high level (8 if possible) Hi-Potion at the end of your deck, so after you use all your cards, you'll be ready to use the Hi-Potion. After that, resume the Sonic Raid spam as usual. Two full decks of Sonic Raids was usually enough to take out any boss before Marluxia's 2nd form.

EDIT: This is only effective as a winning strategy if you have a very large deck and enough cards to have a large number of consecutive Sonic Raids without running out. I roughly recall being able to do 7-8 (give or take) Sonic Raids before having to use a Hi-Potion.

 

Well, I tried that, and it came out well. AND I WON!!!!

Thanks sooo much! I also found that using the Stop>Attack Card>Attack Card sleight is extremely helpful, especially for bosses with low HP. Got to Neverland and got CH down to one and a half bars with that sleight o.o
