Maybank2Cards and Ikhwan MasterCard as suggested above. For first due date, if curious can check with CS. Else, just wait till it's showing in your online banking.
Maybank is so-called one of the better banks in Malaysia which offers good cards.

Forget about HSBC Amanah Power and RHB Smart Value. Make sure you read first how to maximize these two cards. There are existing threads in this section.

No, your card is still active even if you don't activate it. It will still be shown in your CCRIS, especially for your case which is below 36k p.a., you are only limited to two issuing banks. Hence, call to cancel RHB if you don't plan to use it. A piece of advice, RHB will not totally cut it off, so it may be still showing in your CCRIS. So, please have a close monitor on this. This is based on my own experience.

Although I mentioned two issuing banks, the above suggestions for both MBB cards are considered as two entities. One is conventional and one is Islamic, hence if your annual income is not RM 36001 and above, once you apply for these two cards, they will take up your allowable holding cards quota.
