ASCII Cube Encryption (simplification)

X key:
1 or 2 or 3 or 4 or 5
(One number per line or counted and separated by spaces)

Y key:
1 or 2 or 3 or 4 or 5
(One number per line or counted and separated by spaces)

Z key:
1 or 2 or 3 or 4 or 5 or 6
(One number per line or counted and separated by spaces)

Shuffle key:
List a newly shuffled ASCII Cube ordering per message symbol.
(One unique shuffling per message symbol and separated by a blank line)
I know this unique shuffle key per symbol system seems bulky, being
150 times bigger than the message itself, but will provide maximum
security.

The security in ASCII Cube Encryption lies in keeping the four keys
separate from each other, like the multi-key system of nuclear launch
codes.
