The bare minimum for the deck to operate properly is something like 12 Towers/Pends, 6 Shields, 2 Lobos, 4 Dragons, which leaves you 6 slots to play with. Each card you add over 30 basically adds another turn you have to stall without shields, so that's out of the question. There have been a few versions mentioned with different cards in the last 6 slots, but it's always been a combination of SoGs and extra Towers, Lobos and Dragons. If you think something else could work I encourage you to test it out, but if you ask me, I doubt it will win more than the cards already in deck.
