Rivals of Ixalan has provided me with a fantastic support card in Ashes of the Abhorrent!

Im not conviced by your sac outlets to be honest. They all require you to pay mana in order to sacrifice a creature as far as I see.Viscera Seer and Cartel Aristocrat would do a better job in killing your own stuff.

I haven't had any problems with it. Children of Korlis, Selfless Spirit, and Walking Ballista can all sac themselves without use of mana, and Hidden Stockpile replaces the creature at EOT, so the 1 mana is worth it to me. Viscera Seer might be worth it, but I'll have to playtest a little to see where it fits. I don't really want to give up any of my other 2 drops for Cartel Aristocrat. While it does sac creatures, its effect isn't as helpful to my deck. Selfless Spirit is better IMO since it has flying, and can protect all my creatures(if I happen to want them protected). Thank you for your suggestions, lukas96

Well i dont see how you are able to kill our opponent quickly when you only have 3 creatures that are able to kill them selfs because each of them Should only be worth 1-2 life.Those two will make your deck much faster because you can play a spell and sac as many creatures as you want.

Hidden stockpile is decent your right, but it doeasnt have to use its second ability to produce a token so it would be even better with the two suggested cards.

Maybe an Exquisite Blood? Or a Sanguine Bond? Or both?

Or a creature, that is able to sac creatures... Would be a pretty good synergy I suppose.

Fun deck! I love the drain mechanic, how has this playtested?

Forceofnature1, I have made a lot of changes lately, so I haven't fully tested it in its current state. Previous tests and casual play have been encouraging. This is a fun deck to play.
