Well based on the new article:
At least 1 card that directly counters Thad (Tower of Thebez)
At least 2 Two Brigaded card, (Jezabel and Abimelech)
Gibeonite Delegates is likely Generic (So at least 1)
Assuming Kings refers to characters that are kings and not Kings reprints there is 1 and likely 2 in there, (Abimelech and likely King Ahab)
Abimelech is likely warrior class, and if Ahab is printed he will be warrior class
