Grave Tidings (EDH / Commander)

Basic synopsis:

What once started as Ikoria commander pre-con Enhanced Evolution has been completely reformed with a new commander and powerful symmetries. 'Muldrotha, the Gravetide' is the engine that enables a cost effective shell of recurring utility permanents to power control, ramp and +1/+1 counter generation. Ramp includes 'Wayfarer's Bauble', 'Ordeal of Nylea', 'Font of Fertility', 'Sakura-Tribe Elder' and 'Jeweled Lotus' to get and keep Muldrotha online quickly. Draw - 'Mishra's Bauble', 'Implement of Ferocity', 'Mystic Remora' or 'Vessel of Nascency'. Control options 'Executioner's Capsule', 'Seal of Doom', 'Seal of Primordium', 'Pernicious Deed' and well as cost effective creatures 'Siren Stormtamer' and 'Sylvan Safekeeper'. Mutation is re-cast in a supporting role, adding flying, trample and/or removal, plus a generous base boost to +1/+1 encrusted creatures.

Key pieces include 'Gravebreaker Lamia' who tutors to your graveyard coming into play and reduces casting costs from the graveyard by 1. 'Mazirek, Kraul Death Priest' gives +1/+1 to all your creatures each time any player sacrifices anything which synergizes with forced sacrifice enchantments 'Tainted Aether' or 'Desolation', allowing you to grow your forces while simultaneously cutting off your opponents from their resources. This feedback loop also works by sacrificing and re-using your own utility permanents and a host of fetch lands ('Verdant Catacombs', 'Misty Rainforest', 'Polluted Delta', 'Terramorphic Expanse', Fabled Passage'). Further, with 'Titania, Protector of Argoth' or 'Avenger of Zendikar' on the battlefield, each drop, sac & drop fetch land cycle also triggers their own tokens and +1/+1 counters. 'Sylvan Safekeeper' can trigger the cycle while providing shroud to it's parts. Adding 'Exploration' to double land drops and 'Doubling Season' to double token and counter totals further accelerates the process. With 'Champion of Lambholt' on-board gaining +1/+1 counters, your creatures quickly become unblockable.

Other +1/+1 counter and token synergies to watch out for include 'Master Biomancer' + mutation as it grants +1/+1 counters to each creature entering under your control equal to it's power. 'Jarad, Golgari Lich Lord' allows you to sacrifice creatures as a reusable artillery of your pumped creatures. 'Iridescent Hornbeetle' is a ticking timebomb, releasing insect tokens for each +1/+1 counter created while 'The Ozolith' preserves those counters, amassing them to be re-used again.

Instants, sorceries and planeswalkers are scant, but key. 'Crop Rotation' looks out of place but as an instant pulling any land, can provide some interesting utility. Use it early to fix mana, to find and loop 'Strip Mine', or save it to pull a surprise 'Glacial Chasm', absorbing attacks for free, keeping your counter-attack at full-strength. 'Inspiring Call' is both an offensive and defensive bomb in this deck. 'Agadeem's Awakening' can drop as land at any time, or use it to unleash a final wave from your readily filled graveyard. 'Nissa of Shadowed Boughs' plusses to untap land and her easily reached -5 lets you choose a creature from your graveyard or hand to enter play with 2 +1/+1 counters.
