0 - 1 of 1 tags for Varchar and Integer

Hi all,
I am trying to tune a query that quickly spools out during a join on two tables between varchar and integer value.
This is the query I am running:

SELECT top 10 

A.*

FROM DB_1.Event_ATM_Card A

LEFT JOIN DB_2.BKEY_CARD  B

ON A.Card_Id  = B.EDW_KEY

and B.DOMAIN_ID =1
