Holy jesus, my pace in RE:COM has always been 3-4 levels per world so after the 8th world I be at around level 31 which was usually enough. So you being that high should help you cruise through most of the bosses as long as you edit the deck before hand.
For the deck? I've always found it to be preference. I usually just stack my deck with lethal frame, that one sleight with gravity and fire, that fire tornado sleight and then just a bunch of attack cards with 3 cure, 2 potions esque stuff.
It worked for me but I think for you, you can just stick some more attack cards for some easy whacking.
Heh, I guess that came from my excessive grinding in Agrabah for Moogle points with Aladdin (got that 10.000 Moogle Points-trophy by the way) as well as gaining my first few Key to Rewards cards in Atlantica and Neverland which caused quite some backtracking.
Preference is good, I haven't played the game enough yet to form excessive strategies, although I did found that some sleights are particularily effective to clear out whole rooms (if you have six annoying Crescendos hopping around honking their horns off to call reinforcements one Quake will take care of them fast enough). I certainly have not all sleights yet so I won't actually pick a "favorite" deck yet.
I'll probably stick some more attack cards into my regular deck as Bosses tend to be rather unimpressed with Single attack cards even if they have value 9.
I wouldn't call myself a Re:CoM expert, but I know how the game works pretty well.
First off, it sounds like your deck consists almost entirely of cards used only for sleights. It's a good idea to have a lot of sleights set up in your deck, but you shouldn't underestimate what you can do with regular, 3-hit combos. You might think they're weak and do much less damage than sleights, but it depends on which keyblades you use in which order. If you go into Jiminy's Journal, and then go to card index and pick a card, you will see among it's stats: "strike", "thrust", and "finisher", each followed by a letter ranking. "strike" indicates the first attack in a 3-hit combo, "thrust" indicates the second, and "finish" indicates the third. So if a card has a strike rank of D and a thrust rank of A, it will do much more damage if it is used as the second attack of a combo than if it is used for the first. You might consider removing a few sleights and organizing some regular attack cards in an effective order. Also, it is a good idea to level up your CP more often than your health. At 215, I would say you have a good amount and shouldn't need to level it up anymore, if you're good at dodging attacks and navigating your deck quickly. If you have trouble with that, you may need a bit more health. This video demonstrates the concept of using regular attacks in a combo pretty well, so you can use this for reference:

And if you need to level grind for a while to power up health or CP or learn sleights, this video is pretty helpful:

I should have probably said beforehand that this is my primary boss deck, although crowd control is also pretty neat with that one. As I said above, nothing I've seen so far takes care of a whole group of Crescendos (and other ground based foes) as fast as one use of Quake.
For finishing battles quickly, it seems that sleights are indeed the way to go.
Heh, the more you learn. I didn't know about those values of attack cards at all. Might be a fun deck to try out against stronger single foes once I've collected many more attack cards.
So far I have converted every attack (and magic) card of a value less than 5 into Moogle points (except the three 2-cards I use for Ars Arcanum and some 0-cards).
With the onset of the Hi-Potion I even realized that cards "lost" from using sleights, even Premium cards, are not truly "lost" at all because you can even restock those with an Hi-Potion.
Ah, I see that idea was then already on the right track as I assumed that with more CP => more effective deck => Kill foes faster => no need for too much HP.
I actually plan to consequently level up CP more as things go (and use more Premium rooms) until my deck can a) either hold 99 cards or b) the limit of CP is reached.
After the CP-limit is reached, the only thing that remains is leveling HP anyways.
All pretty interesting stuff here. Looks like I need also to study the specifics of the attack cards themselves in the future.
