For those who are wondering, THIS is the deck that always beats and gets EMs against Decay. This deck is the third in the original post. You may see some upgrades here, but it works wonders also unupgraded. Trust me, if this deck is played correctly, 100% of the matches will be EM. only I was lucky enough to never lose and always get an EM with this deck. Unfortunately many other users reported losses with this deck, but it's still my choice for Decay.
My current stats with it: 10-0. 10/10 EM. No changes and no upgrades are needed Put as much upgrades in it as you can! It's just perfect. Thanks go to majofa!

This bow seems to work very well for me as well. Hasn't failed me yet... Although, I do use something very similar to what is shown above rather than a fully unupped version, so the speed may make a big difference.
The strategy seems very solid though.
One thing that may be hurting some players is if they forget to wait to play the golems until they can protect him. If you don't wait, they end up as siphon fodder.
Similarly, its good make sure you either protect your first sanc. with EA or wait till he wastes some of his steals on pillars and hourglasses... Although with that many Quantum Pillars, you should be able to simply outproduce his drain. (8 quantum pillars will outproduce a full field of devourers by a net of +2 quanta, counting mark gen).
