Corinthians are fast fun strong! My personal favorite in clay.
Defense should be able to handle fbtn heroes and have several interrupts
Corinthians are a solid Clay offense. You'll probably need to play Sowing Bountifully in battle thanks to Moses though
I prefer a more splashy Clay offense:
Ephesian Mentor/Apollos
Claudia
Cornelius
Peter/Jude (depending on whether you are playing Crimson heretics/Simon the Magician or not)
Soldier of God/Christian Soldier/Saint of Virtue/Paladin
Epaphras/Philemon/Onesimus
This offense is full of great first-turn heroes and has good speed. It pairs very well with a NT Crimson defense. For the Armor of God heroes, just play Shoes of Peace (the 3/4 that discards an evil card from hand or battle) and Sword of the Spirit. Throw in some interrupts/negates and maybe Eternal Inheritance and call it a day.
