As Throne of Eldraine enters, choose a color. {T}: Add four mana of the chosen color. Spend this mana only to cast monocolored spells of that color. {3}, {T}: Draw two cards. Spend only mana of the chosen color to activate this ability.

Exile all cards from your library. Then shuffle your graveyard into your library.

Imprint — When this artifact enters, you may exile an instant card with mana value 2 or less from your hand. {2}, {T}: You may copy the exiled card. If you do, you may cast the copy without paying its mana cost.

Nonbasic lands don't untap during their controllers' untap steps.

Search target opponent's library for a creature card and put that card onto the battlefield under your control. Then that player shuffles.

Flash When this creature enters, target instant or sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost. (You may cast that card from your graveyard for its flashback cost. Then exile it.)

Search your library for three cards and reveal them. Target opponent chooses one. Put that card into your hand and the rest into your graveyard. Then shuffle.

Enchant creature When this Aura enters, untap up to five lands. You control enchanted creature.
