how about Phage the Untouchable + Platinum Angel

Oh man, absolutely! It's funny, I'd considered Platinum briefly, but excluded it as I couldn't think of anything worthy to mash it with. How I forgot about Phage I'll never know. Added to the board to acquire in the future (as unfortunately I own neither card at this time).
Thanks for the suggestion!

Bro you need a Warchief Giant. Give your Gray Merchant of Asphodel myriad, your Massacre Wurm myriad. IMAGINE. Sepulchral Primordial with M Y R I A D. Oh and Grusilda gives them all menace. ;))))

Whoa. Whoa. Whoa. I don't think my brain can handle the possibilities that has introduced. Bro, you just opened up a whole new realm of insanity. I LOVE it!

No love for Prophetic Flamespeaker?

Great deck btw, I've been waiting for a Strong Monster Masher decklist to show up and yours fits the bill - looking forward to the deck arriving in the mail next week :D

Prophetic Flamespeaker was actually in the initial draft of the deck, as I adore the card in general. The only problem with it surrounded mana and the potential to lose combo pieces for good! I found that I was having to hold my mana strictly to maybe possibly cast whatever he dug out, which would either throw off the plans I'd made for the cards in my hand OR would end up exiling my own important high-CMC cards for good, never to return!
Ultimately, after whiffing with him (and/or assuring my own doom with him) too many times, he simply ended up getting cut- That's actually how Yahenni ended up in the deck, albeit more as a placeholder than anything- He holds a more generically solid and consistent spot for now, although is likely one of the first to be cut once more of the Maybeboard is in my physical possession.
I appreciate you taking the time to make the suggestion, and hope you enjoy the deck as much as I do!

Thanks for the love! And I have not, but definitely intend to now! Seems like it would blast with Torchling as well!

Damn this is an amazing list. Absolutely love it +1

I've added Triskelion to my version of the deck as it combos infinitely with both Flayer of the Hatebound and Murderous Redcap.

@Dtowns- Thanks for the love! Right now the deck is sitting at close to the 75% point, and I'm definitely trying to keep it around that line if possible!

@Rabid- Goddamn. As someone who's played competitve reanimator-style decks in the past, I have no IDEA how I excluded Triskelion. Nice catch, and I'll definitely be finding room for it at some point!

You are very welcome CivilizedSin! Thanks for posting such an awesome list!

I played the deck for the first time today....after winning two pods my opponents were begging me to play another deck lolz

I'm also running Tyrant's Familiar and Inferno Titan due to the amount of damage they deal out (especially when melded)...as the more creatures destroyed = more targets you have to meld with Grusilda ;)

Haha I haven't quite gotten my opponents to that point with this deck yet- I'm pretty close to an X% winrate, where X=(1/[The number of people at the table])*100. I'm definitely happy with that for now, as I believe Un-cards are being re-banned sometime this month, and I would hate to have my pod pull the "well it's banned" argument one day after the amount of work put into this deck, as it doesn't really work with any black-bordered commander!

I like the idea of Tyrant's Familiar, as obviously most of the time the only way it's coming into play is through Momma G. The built-in haste is appealing as well. Inferno Titan makes sense as well, especially with the ability to mash them with Vampire Nighthawk or Gifted Aetherborn. The only problem comes down to figuring out what to pull OUT! I'll definitely put some more thought into it- thanks a ton for the ideas!
