At the beginning of your upkeep, target player mills two cards. If your main library has five or fewer cards in it, that player mills their library instead.

If an opponent would draw one or more cards, that player instead draws that many cards plus one, then exiles a card from their hand.
You may play cards exiled by Curated Citations, and you may spend mana as though it was mana of any type to cast them.

Choose one —
• Counter target creature or planeswalker spell.
• Return target creature or planeswalker to its owner's hand.

Any number of target players mill twice X cards, where X is the number of artifacts and enchantments you control. Then you may cast a nonland card with mana value X or less from a graveyard without paying its mana cost. You can't cast more spells this turn.
