Flipkart axis limit updated to 1.5 L😏

Hi I recently saw various reddit posts of how we can upgrade credit limit. So, I took matters in my hand and guess what got updated limit of ₹1,50,000 from ₹35,000. I think thats great. What dies the community think, shall I also get a core card of Axis(Neo LTF) or is it useless to have? I basically want to have lifetime free cards from now on.
