Chaos Lord has 4 steals, if you're in it to make money quickly, dont waste time on him, he's better off skipped. The last three times I've faced him he has used two early, then saved the last two (plus a deflag on occasion) to take back to back shields. He is on my auto skip list.
also, imo the fat version is better than "fat fat." Having too many cards opens up the possibility of losing due to sheer bad deck order. nothing you can do if you dont draw an hourglass, or a shield until turn6 or 7... Doesn't happen often, but happens more often w/ the fat fat version. Another problem with the 6 sancs is as you get towards the end of your deck, there is a much greater chance of being low on light quanta. Even if you manage your quanta effectively and dont play the sanctuaries if you dont have 13 light quanta yet, you end up losing hourglass draws, and thus precious turns on your shield due to having no space to draw. Then you are faced with the choice, do I risk playing my 4th or 5th unnecessary sanc in order to allow me to use hourglass? because you might draw the 8th card for the combo with not enough mana to play them all.
All in all having more cards also means it takes longer to win (or lose) so overall you aren't saving any time, and in my experience it has slowed me down giving me false hope and prolonging losses due to quadruple trebuchets with a few cards left to go in the deck etc.
