Pick a card from an array in bash


I am trying to use $RANDOM to pick cards from an array in bash. I created the script below to give me a selection everytime I run it, but the output is always like this:
2 3 4 5 6 7 8 9 10 Jack Queen King Ace of Clubs Diamonds Hearts Spades.

Can you please help me? I expected it to give me something like : 2 of Jack or 5 of Hearts, everytime I run it. the codes are below

suite="Clubs Diamonds Hearts Spades"
denomination="2 3 4 5 6 7 8 9 10 Jack Queen King Ace"
echo -n "${denomination[$((RANDOM%num_denominations))]} of "
echo "${suite[$((RANDOM%num_suites))]}"
exit 0

suite="Clubs Diamonds Hearts Spades"

That's not an array:

suite=( Clubs Diamonds Hearts Spades )

That's an array.

Fix both of those and it works great.
