Does anyone know where I can but T11 cards (e.g. Centurions, Guardians) in Dallas, TX (i.e. are there any T11 retailers in Dallas)?
Most brick and mortar shops will place an order for you.
Shane Black is from Texas...he may know if you shoot him a PM.
Or....just buy them here and pay the shipping if you have no other options.

You can go to Forth Worth Magic etc., I am not certain if they carry theory 11 cards. I have seen plenty of custom cards there though.
