It's really hard to flip anything this year ... So many more users doing it and the daily ratings creates a minor impact
Best bets are to flip the new cards introduced every Friday ... And I prefer to flip equipment bcz there aren't near as many people flipping equipment that are looking for players ... And if u don't have a big bank roll then just grind the better players in the lower tiers ... Typically guys w speed can be flipped easily ... Also submarine pitchers like a Neshek are highly coveted
Keep an eye on daddy leagues home page for the cards getting bought up the most that day ... Might help ya ... Far right column of the website shows biggest sellers for the day
