This deck is an alternative take on reanimator sentinel that doesn't splash primal in favour of playing out a bunch of lower cost sentinels that were given buffs, such as extra damage or killers.
In this case, the idea is to play out your parapet sentries and your hotvies to cause burn damage, then to chain revive them to finish your opponent off. It's been teched pretty heavily against Rakano aggro and being able to kill all their 3 health units before they get buffed is so satisfying. Oh, you used a finest hour to save your unit, then finest houred again to kill my parapet? Oh do I have a surprise for you!
There are a few things I want to change with this deck, such as better early game explorers or adding in excavate to reuse shifting sand. It's an idea I got from SkeeJay's Discard Sentinel Reanimator list. In fact you should just run his deck it's much better than mine.
