mtg invasion of cards Theros // Ephara, Ever-Sheltering [March of the Machine] 13 until end of turn Invasion, 53 cards | Magic:

Tomer gives an in-depth analysis of the new Urza precon and provides an optimized $30 and old-border only upgrade list to maximize its power

You'd apply the same kind of logic to something like Delver of Secrets

This can be an especially useful card in decks that already have an expendable board like Anhelo, The Painter or Lagomos, Hand of Hatred, or in spellslinger everything can be reused decks with commanders like Kess, Dissident mage

However, the high life cost to activate her ability without black mana means she is most reasonable in a black deck

You'll cast powerful spells, call upon classic summons, and even visit your favorite locations on the back of a Chocobo

Venom, King in Black is just another alternate version, and its a premium reprint too
