Tried this too, since I basically had all the cards anyway. I think a small version is much more betta. I like the versions on page 4. 35 max, a pair of everything except 3 damage dealers, and draw draw... No need for a single loboman. It is good in many decks, so either use 2 or drop it. You will never draw just the one when you need it...
It is just not as good as other shields, except against some gods. (paradox LOL) Mostly you can't take all that damage. It is not long ago that I made a deck with this shield and all kinds of damage. Didn't work. Also, stalling doesn't work. (No attack is no damage from the buckler.)
Anyway I won a few times. It's fun, but I see no way to improve it.
