I've also been experimenting with an equipment deck lately but it never seemed like a good enough contender for anything but the most casual games. My effort is here, I'm going for a double strike theme as you can see. I try to get more value from the saboteur effects.
I'd consider removing the benevolent blessings in favour of apostles blessing if you're afraid of losing your creatures. Goblin gabeleer seems like a bad creature to me except when it's able to end the game as it will die before providing you enough value otherwise.
