Cool ! I hope you enjoyed it here . Yeah , there are a lot of screamers at night . even rabbits and loons can sound terrifying when you ' ve never heard them before , or when you ' re in a tent in the dark with no sign of civilization around . I live in a small city nearby , and even the small patch of forest behind my place is teeming with wildlife , and I ' m always hearing terrifying brawls go down . And yes , you ' re correct , there is a lot of untouched land up here , places where men haven ' t set foot for years . It does make one wonder what ' s hiding deep in the Adirondacks . <| sep |> Hi thereI ' d like to offer some thoughts on the deck . Mana BaseFast mana is a huge deal in this format and you ' re playing GBLlanowar Elves , Elvish Mystic , Fyndhorn Elves , Birds of Paradise , Elves of Deep Shadow , Arbor Elf , Priest of Titania , Joraga Treespeaker , Bloom Tender , Deathrite Shaman , Carpet of Flowers are all a great way to accelerate the deck early and most of the dorks can be fed to later if you don ' t need them anymore . Pick a handful of those based on budget and slotsRegarding the lands 38 is really high , if you run fast mana and dorks you can easily go down to 3234 . Slow lands are not good and the worst of them are the bounce lands such as Golgari Rot Farm imagine being hit by a strip mine and set back 2 turns . I ' d cut everything that enters the battlefield tapped unconditionally . The best stuff you can run are fetches , the old duals and shock lands . Now since some of us are not bathing in money , a start would be the following Replace all the bad lands Vivid whatevers , Foul orchard , the cycling lands , Golgari whatevers with basics . Then , based on budget , look into the following , Overgrown Tomb , Gaea ' s Cradle , Llanowar Wastes , Mana Confluence , City of Brass , Phyrexian Tower , Nykthos , Shrine to Nyx , Twilight Mire , GiltLeaf Palace all on color fetches . Playing against many playersSadistic Hypnotist ist nice , though I feel it ' s stronger in 1 v 1 . For multiplayer I ' d run . This card is ace in Meren . Likewise and Bane of Progress are strong , depending on what your opponents run . Win conditionsOverall I feel your deck could be more streamlined . You have a lot of interactions that you say can be hard to assemble . I ' d cut down to an essential 23 that straight win you the game such as your Exsanguniate combo , but add in more fast mana , tutors green has all great creature tutors , black has all great tutors in general , more disruption . For each card evaluate whether it wins you the game , provides a resource advantage or keeps your opponents from winning . If it does nothing of this , cut it . The higher the mana cost , the more sceptical you should be towards a card . Take for example Grim Flayer Fantastic card in 1 v 1 Jund , but I don ' t see it doing much at a table with 45 people , each at 40 life . The standard wincon for Meren is the Necrotic Ooze , , Phyrexian Devourer combo enabled by Buried Alive and as a backup , Mikaeus the Unhallowed enabled by Tooth and Nails . The first one kinda sucks in 5 player games because your library may not contain enough CMC to kill the table . It may be worth considering Jarad as the commander because he ' s a bit better at nuking 5 players . If the exansguinate combo works great in your meta run it . I ' m a bit sceptical because it Meren does not recur it and I ' d rather run it in a BW shell because green cannot tutor for it . Straight upgradesViridian Zealot could be Caustic CaterpillarBlood Bairn could be Carrion FeederMaybe take a look at existing MerenJarad primers for additional ideas ? That ' s my rambling for now .
