Fairly simple deck. Last weekend I went about 20-5 with it, maybe just lucky. Ubsat (Tasbu spelled backwards) or as I like to call him, Upset, played on turn 4 or 5 will usually give you an auto-concede, obviously especially playing against another mono deck. Alhed gets huge, and decay stops zombies coming back. Giving killer to a Dawnwalker is always useful, especially when you have Grodovs Burden up. Pause for reflection can save a small guy, or better used for Friendly Wisp to draw 2 more cards. And the giants, well, are just giants. You may use the time stranger, but I didn't have room for him. I prefer Alchemist for fixing and control.
I chose the usual great time cards for market, but you can switch Hall of Lost Kings for Swirl of Sands or something else. I keep it because I usually have more than 25 hit points with Pause and Upset, and menacing giants that force opponent to use control on their turns. Then boom 5 5/5 sentinels to make it worse :p but keep the site, it makes units cost 1 less.
I was going to keep this deck to myself because I brewed it myself, but hey, if I can help at least 1 person out, I feel better :) Take care, let me know what you think
