This deck was inspired by kobisjeruk's 500EM deckout deck. I didn't want to hijack his thread, so I started this new one. My objective was to create a deck with a higher win percentage and quick games than kobisjeruk's deck. This is what I came up with:

Rather than waiting for the half-blood to deckout, the goal is to kill him using one or more Titans. Assuming the half-blood has no healing ability, it will take 25 turns to fully kill the half-blood after a titan is played. Use the flying weapon to play a second Titan if you need to deal more damage. Use your hourglasses wisely so that you get all your stone skins and SODs played before you kill him. Because the final blow is coming from a weapon and not a creature, your SOGs will heal you on the final turn giving you an EM. As a back up, keep the miracle or one stone skin in your hand to play on your final turn (if a stone skin increases your life above 500, your health will be automatically reduced to the maximum 500). The eternity and "creature" are there just as a backup in case you play too many cards with the hourglass or the half-blood heals itself. Plague is for taking down creatures with momentum or zero attack (fate egg or pest w/ butterfly effect).
I've played this deck 45 times and have won 35 times with 500 health EM. I've only lost 6, which is a win percentage of 87%. The average time per game was 7.16 minutes (average time for 500EM win was 8.75 minutes). Average winnings per game was 218 electrum coins and a 500EM win from a half-blood increases your score by 165. On average, the half-blood had 15.9 cards remaining in its hand at the time of the 500EM win. Thus, this deck saves you almost 16 turns compared to kobisjeruk's 500EM deckout deck.
EDIT: Given the change to stone/granite skin, I've made a couple revisions to the deck.
