Omniscience [Best Game Ending Enchantment] Magic: The Gathering is largely defined by its mana economy
You dont even have to go infinite, but it sure helps
Since you have to cast something to trigger heroic, this should leave your hand card-neutral
Sylvan Safekeeper You need some synergies to want Sylvan Safekeeper, but it shines in decks that want lands in the graveyard
A photo, your own artwork, an alter you commissioned, a custom Commander you dreamed up, or any card you can imagine
That means at higher rarities: Cloud, Midgar Mercenary Gilgamesh, Master-at-Arms Firion, Wild Rose Warrior (free 1/1s with job select) Freya Crescent Giott, King of the Dwarves Adelbert Steiner Zidane, Tantalus Thief is also an exceptional card, even without any direct synergy
