With that, I am proposing five affordable cards for each of the Commander decks that might just make them a little better (a better win-rate is still not guaranteed, though please don't come after me)
(It's not a creature.) Enduring Vitality Rarity: Rare TYPE: Enchantment Creature SUBTYPE: Elk Glimmer CMC: 3 Mana cost: USD: $73.48 EUR: 22.43 TIX: 0.02 EDHREC RANK: 477 (3/3) Vigilance Creatures you control have " : Add one mana of any color." When Enduring Vitality dies, if it was a creature, return it to the battlefield under its owner's control
Further Upgrades The first cards I'd pick up to further juice up the deck would be untapped mana-fixing lands: Watery Grave, Shipwreck Marsh, Underground River, Morphic Pool, Darkslick Shores, Polluted Delta, Sunken Ruins, Undercity Sewers, Urborg, Tomb of Yawgmoth and then maybe a couple more Island / Swamp fetches
Lets say you sit down at a table with a Simic ramp player, a Selesnya tokens player, and someone else
Please do not make any claims or returns after purchase
It has an admittedly narrow use case, but tripling your attack force ends games quickly, and it helps generate long-game advantages with cards like Solemn Simulacrum and Baleful Strix
