I usually avoid EFL cards and I'll probably wish I had later but couple of games I like today.
Watford and Birmingham are the two most booked teams in the Championship. A card each and 3+ match cards is 10/11, 2 cards each is 7/2.
South Wales derby later too (5 and 7 in the booking table), 2 cards each 21/10 - last two meetings, including one with no fans, have finished 4-2 on yellows (a red in one of those too)
Player-wise, Maxime, Hughes and Sarr look the value in the early game so I've got the trixie on that, will edit if any aren't playing. Sarr has 6 in his last 20 so 7/1 looks the stand-out price there.
