Deck History and Summary:
As part of dismantling Alesha, Who Smiles at Death i took it upon me to build both a (B/R) and (W/B) deck. For (B/R) is was considering Xantcha, Sleeper Agent and especially Vial Smasher the Fierce for a while. I really liked the randomness, but the actual lists i came up with didn't entertain me as much.
Unsleeving the dismantled deck Grenzo, Dungeon Warden got stuck in my hand, so i decided to roll with him as a makeshift commander. Guess what, i liked him a lot and decided to make him the permanent commander.
Me not being too much of a combo guy i tried to keep it simple. The deck's supposed to work with Grenzo, Dungeon Warden sitting at a power of 2 and for the future i'd really like to go up to 50 fetchable creatures to maximize hits. Discounting Purphoros, God of the Forge and Homura, Human Ascendant i'm sitting at 45 right now. To be fair, i think finding cuts would be the harder part than finding creatures to add.
Let me know what you think of the deck! I'm always happy to get input.
I am not a fan of the one-off mana generators so I would be curious to know how well they work in practice. In most cases, it seems like it would be better to just have a better creature in that slot. If you want to go further into the death triggers like Cutthroat and Vindictive Vampire, it seems like you could use more sac outlets (like Viscera Seer or Carrion Feeder) and maybe even add in Nim Deathmantle. With either of the 2 Priests, you can't quite go infinite since it costs 1 mana each iteration, but you can get quite a few death triggers with each Priest paying for most of the ability of the Deathmantle.
I question the usefulness of Moggcatcher since you have a total of 5 Goblins from what I can tell. On the other hand, Goblin Ringleader is interesting in this build since you don't want to get Goblins and instead want to ship things to the bottom of the library. Grave Defiler is similar as you only have 4 other zombies. I like them both.
Hmm, Nim Deathmantle you say? I mean, my actual plan is finding more slots for creatures, so it'd be extra hard to find a slot for it. Not too convinced it's worth it either. Free sac outlets combined with the common bottom-of-library tools should do the trick.
The Dragon seems decent. It is a bit more limited in that you need Threshold so it is easily turned off and it is just one creature. The Priest is 7 power across two creatures and, with some shenanigans, you can get more than just one 5/5 flyer from it. I do agree that the Dragon is cheaper to get out but I think there is potentially more utility in the Priest. I think either one can help if you need a decent flyer.
Nighthowler and Wight would likely be the 2 best cards among this list. I think the others are much too expensive and, as you mentioned, without evasion. Wight and Nighthowler are without evasion too but Wight is super cheap and Nighthowler can, in a pinch, be attached to something with evasion.
I can understand that. I think the Mage slightly has it over the Riders due to mana cost and being able to control when you blow up a land, but if supply is an issue, Riders is serviceable. I know when I built my Alesha deck I did something similar where I only included 1 or 2 just to have them rather than an entire suite.
I usually prefer Viscera Seer and Carrion Feeder due to their low cost. Yahenni, which you have, is higher on the curve but it also easier to keep around which I think makes it a good card to include as well.
Another card you can look into is Noosegraf Mob to get you a bunch of tokens to go wide with. And, once you have your army, you put it on the bottom and get it back with Grenzo to start everything over again. 6 mana is a lot to try to hard cast it but it can get be pretty good if you can manage to cheat it out early.
