Hey guys! This is my first full-out deck guide, so here we go!
The Main Idea:
To almost all players, this deck looks like standard Undead Decay for the first 7 or so turns. However, your trump card lies in order. This deck focuses on rapidly decreasing countdowns of cheap undead units with abilities like Slayer by utilizing Restless Bones, Flesh Animator, and of course, Blessing of Haste.
Important Concepts for playing this deck:
As with Undead Decay, don't drop a revenant first turn. Please. Make use of each of your units' deaths, if they have to die. You have the Anima Conduits, the Harvesters, and the Rot Eaters, so at least get a small buff out of it. :)
Don't break out the blessing of haste unless it is to destroy a pivotal unit such as a buffed 1 CD creature or to gain a lot of board control. Don't do this 2nd turn to take out some opponent 1-drop. You only have 3, so you should save them for important units like Flesh Animators.
Anima Conduit :
These are very important! If you have some creatures who will die on the next opponent turn, there's no better revenge killer than a Revenant. Don't sack these, as they are vital to regain board control!
Irva, Voice of the Dead - (Ilmire's Husk Whisperer) :
Standard in any Undead Decay. Don't drop her until you know an undead will attack, or if you know she won't be killed. She has a massive target on her head because of her potency.
Monstrous Brood :
You won't end up playing this a lot, but it makes an excellent conditional scroll. If your opponent clears your board with something like Quake when you have a Anima Conduit out, simply play this on one of the resulting Revenants and get board control again! It's a niche card, but i like it and have won using this strategy before.
Blessing of Haste :
Like I said earlier, please reserve using this for regaining board control by killing pivotal units or playing it on a Flesh Animator. It's a nice way to count all undead down very quickly.
Things to Note:
As with all Undead Decay, this deck struggles vs. Energy due to the damaging spells and the dreaded State Machines. Against Growth, try to use your Soul Steals on either Kinsfolk Braves or Vaettrs, as they can be dangerous in the long run. This deck can usually play pretty well against most order decks. Be wary of Decimations and CD reductions.
