I would recommend Cankerbloom over Caustic Caterpillar, because, while the latter creature has a higher initial cost, the cost of using its ability is lower, which likely shall make a major different over the course of a game.

I have replaced Growing Ranks with Nesting Dovehawk, since the latter card is a creature, and this deck has a great emphasis on creatures.

I have replaced Fists of the Demigod with Altar of Dementia, as the latter cards gives this deck both an additional sacrifice outlet and an additional way to put creature cards into my opponents' graveyards, for me to steal with Tariel.

griffstick, FormOverFunction, that is very good, so I shall make that replacement.

I definitely am interested to see how the opening of omenpaths between planes shall affect the multiverse, but I am worried that the planes may start to feel less distinct from each other, as inhabitants of each plane visit others, because one of my favorite aspects of this game is how each plane feels unique and has its own identity, and too much crossover between the planes could cause them to feel too similar and less distinct from each other.

What does everyone else say about this? Will each plane still have its own distinct identity?

scotchtapedsleeves, I actually replaced Glory of Warfare with the feast, since the former enchantment was simply not a good match for the deck's theme, but I would sooner remove Fists of the Demigod over Scourge of the Nobilis, since the scourge can be quite powerful, in certain situations.

I am contemplating putting a copy of Altar of Dementia into my Tariel, Reckoner of Souls EDH deck, likely replacing either Searing Meditation or possibly Fists of the Demigod, but I wish to ask the other users here for advice, before I do that.

Since that deck focuses on stealing my opponents' creatures for both combat and sacrificing, AoD would provide both an additional sacrifice outlet and an additional way to put creature cards into my opponents' graveyard, for me to steal, which is obviously a good thing.

What does everyone else say about this? Should I put Altar of Dementia into my Tariel deck?

Necrosis24, that sounds good; thank you, very much.

On a different subject, how likely is it that WotC may print a creature that is identical to Doom Whisperer, except that it has scry, rather than surveil?

I am considering putting Doom Whisperer into my Liesa, Shroud of Dusk EDH deck, because of its obvious synergy with that deck, but I would like to ask for advice, first.

The demon would be an easy replacement for Crystal Ball, because, while it does have a higher casting cost, its ability costs no mana, only life, which this deck excels at gaining. If the demon had the scry mechanic, rather than surveil, I would already have had it in that deck, but, since that is not the case, I need to be more cautious.

Does my Liesa deck have a sufficient amount of graveyard recursion to justify putting Doom Whisperer into it? What does everyone else say about this subject?

I have replaced Glory of Warfare with Feast of the Victorious Dead, which decreased this deck's average converted mana cost from 3.87 to 3.84, since the latter card better fits the theme of the deck than did the former card, in my mind.

Should I put Altar of Dementia into this deck? That would give this deck an additional sacrifice outlet, and also put more cards into my opponents' graveyards, for me to steal with Tariel.

scotchtapedsleeves, I definitely thank you for your feedback, but I do feel that there are significant similarities between those two decks, so I do not see a problem with putting the feast into both of them.

I would recommend either Eternal Witness or Cosmic Rebirth over Regrowth, unless having a low mana curve is important to this deck.

May I ask what the general theme of this deck is?

Also, why have you lost your fondness for the Forgotten Realms setting? I enjoyed it quite thoroughly.

I would like to put Feast of the Victorious Dead into these two decks, but I am not certain what cards to remove from those decks to make room for the feast.

In my Tariel, Reckoner of Souls deck, I feel that Glory of Warfare may be rather expensive (although I admit that Fists of the Demigod or Searing Meditation may also be rather superfluous in that deck, as well; Pain Magnification at least helps to fill my opponents' graveyards, for me to plunder them), but I am less certain about my Teneb, the Harvester deck; I am not certain that that deck contains a sufficient number of artifacts to justify it containing Glissa, the Traitor, but she also is an easy way to get creatures into my opponents' graveyards, for me to then steal with Teneb.

What does everyone else say about this? Should I put Feast of the Victorious Dead into those two decks?

Gidgetimer, that is very good, because that is exactly how I was hoping that it would work; thank you, very much.

Gidgetimer, so, which ability would be put on the stack first, and which ability would resolve first?
