Some suggestions that might work..
1. Caltrops would be nice against swarm and not totally bad with no Humility against 2/1 creatures. Has a lower casting cost over wrath of god but wrath of god is still good since caltrops requires a combo to work.

2. 4 Humility and 4 Moat i think is a must

3. Smokestack maybe 3 ? since its clock became abit slower without Magus + Geddon to wipe creatures on the board. Opponent could just cast creatures after creatures so that they wouldn't suffer the smokestack until they get or find a way to remove the humility / moat.

4. Faerie decks would be a problem with no humility.

5. For me sphere of resistance would work better over sphere of law.
