mtg god commander deck Esika EDH | 5 Colour Legendary Deck When God God-Eternal Oketra

Necropotence is black's best card-drawing effect, and thats precisely what combo decks are looking for

Each of those, like the Darkness Crystal, will reduce the mana required to cast a spell in its appropriate color by 1, and will cost four mana two of the color of choice, but the rest is unique to each Crystal

Two of its modes are two for ones and the steal ability has multiple relevant targets in Modern, so I would recommend playing this card in most decks which are able to pay for its restrictive mana cost

Zell is probably a fine inclusion in most red decks, but it really excels in red/green landfall where multiple landfall triggers each turn help you to press your advantage much more effectively
