Create four 1/1 red and white Warrior creature tokens.

Exile the top three cards of your library. For each land card exiled this way, create a colorless artifact token named Lotus Petal with “{T}, Sacrifice this artifact: Add one mana of any color.” Until the end of your next turn, you may cast nonland cards exiled this way.

(Activate each ability only once as a sorcery. You gain the realm's favor after activating them all.)
{G}: You may play an additional land this turn.
{1}{G}: Search your library for a basic Forest card, reveal it, put it into your hand, then shuffle.
{2}{G}: Search your library for an Elf card, reveal it, put it into your hand, then shuffle.
Favor — Whenever you cast an Elf spell, draw a card.

Return target nonland permanent to its owner's hand.
Dominance — If you control the creature with the greatest power or tied for the greatest power, you may put that permanent on top of its owner's library instead.

Exile up to one target creature or planeswalker. Its controller gains life equal to its mana value.
Orchestrate {W} (You may exile this card from your hand any time 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.)

Tap target creature. Prevent all damage that would be dealt to and dealt by that creature this turn.

Submerge target spell. (To submerge a card, exile it, then put it on the battlefield face down under its owner's control as a 2/2 creature.)

Counter target spell. Create a 1/1 blue Elemental creature token with flying.

When Lost Empire's Legacy enters, create two Treasure tokens.
{1}, {T}, Sacrifice an artifact: Return target artifact card from your graveyard to your hand.

Enchant opponent
When Lost Knowledge enters, enchanted player reveals their hand.
{1}, Sacrifice Lost Knowledge: Scry 2, then draw a card.

Choose two —
• You gain 3 life.
• Lost Memories deals 3 damage to any target.
• Investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)

Counter target spell, activated ability, or triggered ability. Its controller chooses draw step, main phase, or combat phase. That player skips each instance of the chosen step or phase during their next turn. (Mana abilities can't be targeted.)

Glitch {2} (Remove one [restriction] for each time you pay the glitch cost.)
Put target creature [spell] on top of its owner's library.

Lost Station enters tapped.
{T}: Add {U}.
{U}{U}: Until end of turn, Lost Station becomes a 2/2 Horror creature with “This creature can't be blocked.” Activate only if you're horrific.

Counter target spell. If a noncreature spell is countered this way, conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

Target player discards two cards.

Exile target nonland permanent.

Put target nonland permanent on top of its owner's library.
Create a colorless artifact token named Lotus Petal with “{T}, Sacrifice this artifact: Add one mana of any color.”

Target creature gets +2/+2 until end of turn. Untap it.

Look at the top three cards of your library. Put one of them into your hand. Put Lost in Deep Storage and the rest on the bottom of your library in any order.

Enchant creature
Enchanted creature can't attack or block, and its activated abilities can't be activated.
Mirage {W/U} (You may cast this spell as though it had flash for its mirage cost. If you do, sacrifice it at the beginning of the next cleanup step.)

Exile target permanent. Return that card to the battlefield under its owner's control at the beginning of the next end step.

Creatures can't attack you or planeswalkers you control unless their controller pays 2 life for each of those creatures.

This spell costs {1} less to cast if you've cast another spell this turn.
Destroy target creature.

Play with the top card of your library revealed.
You may play the top card of your library.
At the beginning of your end step, create an X/X green and blue Plant Elemental creature token with reach, where X is the top card of your library's mana value.
