I get a hand that's perfect (5)
I believe the answer is:
ideal
'perfect' is the definition.
(similar in meaning)
'i get a hand' is the wordplay.
'get' is a charade indicator (letters next to each other).
'a hand' becomes 'deal' ('deal' can be a synonym of 'hand').
'i'+'deal'='IDEAL'
'that's' is the link.
(Other definitions for ideal that I've seen before include "without flaws" , "Optimum" , "just the job" , "Very eager (to see)" , "Model of ethical behaviour" .)
