Seeking a replacement recommendation for axis vistara

I was using the axis vistara card and was very happy with the returns in terms of business class tickets, gold membership, business lounge access

Now post the air India merger, there is no clarify on what will happen to the benefits post this billing cycle.

My spends are 20-30 L per year. What would be the best credit card combinations for me. Key categories for me are travel, online shopping and offline dining.
