Infinite nostalgic mana

Choose one — • Untap all lands you control. • Until end of turn, lands you control become 2/2 creatures that are still lands. Entwine (Choose both if you pay the entwine cost.)

Imprint — When this artifact enters, you may exile two target sorcery cards from a single graveyard. Whenever a player casts a card, if it has the same name as one of the cards exiled with this artifact, you may copy the other. If you do, you may cast the copy without paying its mana cost.

As an additional cost to cast this spell, discard X cards. Return X target cards from your graveyard to your hand. Exile Nostalgic Dreams.
