When Taken Away enters, target opponent reveals their hand. You choose a nonland card from it and exile that card until Taken Away leaves the battlefield. You may cast that card for as long as it remains exiled, and you may spend mana as though it were mana of any type to cast that spell.

Until end of turn, noncreature lands you control become 3/3 Elemental creatures with haste and trample.
Orchestrate {1}{G} (You may exile this card from your hand anytime you could cast a sorcery for its orchestrate cost. When you next resolve a spell, you may cast this from exile without paying its mana cost.)

Whenever Talent Scout enters or dies, return target creature card with mana value 2 or less from your graveyard to your hand.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)

Draw two cards, then discard a card.

Archive 3 (As this enters, shuffle the top three cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever a source you control deals noncombat damage to a player, draw a card from the archived library.

Deathtouch
Breach (Whenever this deals combat damage to a player, you may have it become an Aura Curse until your next turn. Attach it to that player.)
Whenever an opponent has less life or fewer cards in their main library than the number of Curses attached to them, they lose the game.
