Card game rather poor without clubs (5)

I believe the answer is:

rummy

I'm a little stuck... Click here to teach me more about this clue!

'card game' is the definition.
(I know that rummy is a type of card game)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for rummy that I've seen before include "Odd; card-game" , "with an alcoholic taste?" , "Gin perhaps?" , "game of cards" , "Two-pack card game" .)

I've seen this clue in The Times.
