Grave Tidings v4 (EDH / Commander)

Basic synopsis:

All permanents build favoring clever & curious board states and interactions vs. a more typical stax Muldrotha approach.

'Muldrotha, the Gravetide' enables a shell of recurring utility creatures and permanents to power control, ramp, +1/+1 counter effects and discard paths to a variety of win-cons. Ramp options include 'Wayfarer's Bauble', 'Burnished Hart', 'Font of Fertility', 'Sakura-Tribe Elder', 'Uro, Titan of Nature's Wrath', 'Gemstone Caverns', 'Lotus Petal' and 'Jeweled Lotus' to help get and keep Muldrotha online. Card draw - 'Mishra's Bauble', 'Implement of Ferocity', 'Psychic Vortex', 'Vessel of Nascency', 'Secrets of the Dead', 'Geier Reach Sanitarium' or 'River Kelpie'. Direct removal options include the seals 'Seal of Doom', 'Seal of Primordium', 'Seal of Removal', also 'Bane of Progress', 'Plaguecrafter', 'Bone Shredder', 'Binding the Old Gods', 'Amphin Mutineer', 'Skemfar Elderhall' and 'The Eldest Reborn'. Counterspells and Protection include - 'Siren Stormtamer', 'Sylvan Safekeeper', 'Spore Frog', 'Dark Sphere', 'Energy Field' as well as Aura's 'Journey to Eternity // Atzal, Cave of Eternity', 'Lilting Refrain' and 'Zur's Weirding' (use life to counter threats coming into play, while Muldrotha removes the threat for you).

Tutoring is managed by 'Defense of the Heart', 'Oriq Loremage' and key lieutenant 'Gravebreaker Lamia' who also reduces casting costs from the graveyard by 1. 'Mazirek, Kraul Death Priest' is a good early play giving a +1/+1 counter to each of your creatures, each time any player (including yourself) sacrifices anything which synergizes with Muldrotha's recursion of sacrificial utility permanents (like 'Implement of Ferocity, which also gives it's own +1/+1 counter and draws a card), fetch lands and 'Lonis, Cryptozooligist'. 'Tergrid, God of Fright // Tergrid's Lantern' lantern side adds to the sacrifice strategy. 'Geier Reach Sanitarium' also forces draw and discard. Multi-purpose discard options include 'Jace's Archivist', 'Plaguecrafter', 'Daemogoth Woe-Eater', 'Zur's Weirding', 'The Eldest Reborn' and slow-burn rattlesnake 'Lilting Refrain'.

Finally, only one non-permanent is found in this deck: 'Primal Surge' can trigger a game ending wave of your entire permanent-based deck entering the battlefield with 'Laboratory Maniac' emerging as win-con.
