Does the total number of cards in both groups have to be even? If yes that is an impossibility, 33 is not an even number
OR
are you only speaking of even number of inverted cards in both groups? that is an impossibility again because 11 is not an even number either

But if you are saying that out of 33 cards two groups are made, let's say 20 and 13 and they both have 6 and 6 inverted cards, it makes a point, but that also means the inverted cards exceed 11.

What the odd number a catch?
