Disbanded in an effort to cut down on EDH decks and make room for new ones (nothing to do with playability). If we want to play this again, we'll rebuild it anew.

Meren is still one of the most powerful commanders, yet I've had trouble getting wins with her. Deck's not bad by any means and much more streamlined, I may have expected a little more. May reassemble someday.

======================

SUGGESTIONS:
In addition to the ideas below, this:

(also discusses cutting spells with sacrifice to add creatures with sacrifice)

- Removing mana dorks and replacing them with (dispensable) creatures instead as it will easily ramp you experience counters. Strategy early game should be ramping experience counters anyway, not mana - we cheat stuff into play from our yard or hand.
CARDS: Devoted Druid, Burnished Hart, Farhaven Elf

- Check which cards do not do anything with either sacrifice, or answer nothing. Ignore big bombs / finishers here.

- Add sacrifice beneficial cards.
Ashnod's Altar (we have 1), Evolutionary Leap (cheap, allows us to cycle through our deck for creature cards), Grim Haspurex (grants us cards), Rescue from the Underworld (sac 1 to return that + another one)

- Add enter the battlefield beneficial cards.
CARDS: Ravenous Chupacabra, Solemn Simulacrum, Disciple of Bolas (on enter: sac something else for life and cards equal to its power!)

ALSO INTERESTING:
- Nissa of Shadowed Boughs (cheat stuff in game)
- Syr Konrad, the Grim (could replace Extractor Demon)
- Golgari Findbroker
- Jarad's Orders (tutor, puts one in graveyard)
- Priest of Forgotten Rites
- Deadbridge Chant (self mill 10, then at upkeep: return a random card to hand, or to battlefield if its a creature!)
- Deathsprout
- Spark Harvest (sac a creature to destroy creature or planeswalker)
- Krosan Wayfarer
- Fecundity

CONSIDER REMOVING / REPLACING:
Tribute to the Wild (unsure. It's instant speed ench/artifact 'removal')
Thought Vessel (mana rock and no max hand size... do I need this?)
Extractor Demon (maybe, I can mill peeps with this, but it has a high CMC and does not win us the game. Syr Konrad is more effective?)

Casualties of War - Wipe one of each permanent type.
[29-01-2021] I had two Primal Growth in my deck at some point. I forgot to note that in Deckbox, but I've replaced one with Casualties of War.
[26-08-2022] I applied this, not pending anymore

- Vraska, Golgari Queen
- Dictate of Erebos - MUST INCLUDE.

- Primal Growth - Kicker to sac a creature to search for two basic land cards instead of one.
- Pattern of Rebirth - Very strong recycle enchantment aura. On death, search for creature in library and put into play.
