Oona, Queen of the Fae Oona, Queen of the Fae not only takes resources away from your opponents, but it can also make you a lot of tokens, especially if youre facing at least one mono-color deck
You sacrifice one artifact, then bring back another from your graveyard directly onto the battlefield
Its elegant and something I can really get on board with
Cards like Kozileks Return and Fatal Push, whilst powerful, arent as important for dealing with early creatures as they used to be, thanks to the printing of Walking Ballista naturally providing the mono-green version of the deck with built-in small-creature removal
Many decks that would seek to cast powerful 3-drops on turn 2 cannot take advantage of these creatures reliably due to inconsistent mana, so going big with mono green seems like a great way to go.
Since youre casting the spell from exile, it seems perfectly suited for decks like Prosper, Tome-Bound alongside cards like Wild-Magic Sorcerer and Passionate Archaeologist
