Wanted to get your recommendation on the credit cads I should be getting.\u201d\n\nYou can safely assume he\u2019s looking to optimize rewards on only this spending and that his personal spending is already taken care of by other cards. You can also assume credit score won\u2019t be an issue.\n\nWhich cards should he get and what is his EV from using these cards on the $50K of purchases he mentioned?",
