So do I. Let's talk about one in particular: Ashen Rider
I have played this in place of Flayer of the Hatebound in a bundle of matches this week. I thoroughly enjoyed it and did not wish it was Flayer at all. I tried out this route after reading about user laststepdown's experience with it starting here. I must agree with his logic and note that Ashen Rider enhances two poor matchups in particular that Flayer does not, Sneak/Show and Lands.
Here is a list of pros and cons for you to contemplate.
Pros:
--Rids you of game-losing permanents such as Sneak Attack, Omniscience, Emrakul, Griselbrand, Marit Lage tokens, The Tabernacle at Pendrell Vale, Glacial Chasm, and other stuff.
--Plays well with Bridge from Below.
--Exiles two permanents with a Therapy or second Dread Return. Sometimes exiles three or more permanents with both in your graveyard.
--Is a nice surprise vs. Exhume.
--Pitches to Ichorid and Contagion, or Sickening Shoal to kill a Griselbrand.
--Makes your opponent concede the game.
Cons:
--A hot Reanimate/Animate Dead target vs. Reanimator.
--Does not win the game the same turn he/she comes into play.
--Removes only one/two/three problematic permanents at a time.
Here is what Flayer of the Hatebound does for you.
Pros:
--Might win the game in the same turn with enough Amalgams or a second Dread Return.
--Sweeps your opponent's board of creatures.
--Has the undying mechanic.
Cons:
--Does not remove any of those stupid permanents I listed above.
--Does not pitch to Ichorid, Contagion, or Shoal.
--Does not play well with Bridge from Below.
One must ask themselves whether they actually do win, or can win, more games with a returned Flayer or an Ashen Rider. Certainly there are not enough recorded matches to tell for sure, but I wager to you that the numbers are close if not heavily in Rider's favor. The lesson from my experience is that once Rider is returned, winning the game is quite elementary. This is what you want out of a maindeck Dread Return target anyway. I believe that this is a compelling case to play Ashen Rider in place of Flayer of the Hatebound. Let's see what others have to show for it.
Edit: I fully back this up with another 5-0 on MTGO. The maindeck's changes from the last one:
-1 Flayer of the Hatebound
-1 Contagion
+1 Ashen Rider
+1 Dread Return
