When Lammasu Roost enters, create a 2/2 blue Lammasu creature token with flying.
{3}{U}: Scry 1. (Look at the top card of your library. You may put that card on the bottom of your library.)

{T}: Add {R}.
Whenever you cast a spell from anywhere other than your hand, copy that spell. You may choose new targets for the copy.

Choose one —
• Destroy target artifact. Lamplight Explosion deals 1 damage to each opponent.
• Lamplight Explosion deals 1 damage to each creature your opponents control.

{T}, Pay 1 life: Add {U} or {R}.
{2}, {T}, Sacrifice Lamplit Thoroughfare and another permanent: Draw a card. Activate only during your turn.

Gain control of target land.

Reveal the top four cards of your library. You may put a creature card and/or a land card from among them into your hand. Put the rest into your graveyard, then discard a card if two cards were put into your hand this way.

Search your library for a basic Forest card, put it onto the battlefield tapped, then shuffle.
Dominance — If you control the creature with the greatest power or tied for the greatest power, also search your library for a basic non-Forest card, reveal it, put it into your hand, then shuffle.

Choose two —
• Counter all spells that target you, a spell you control, or a permanent you control.
• Creatures get -2/-0 until end of turn.
• Create two 1/1 white Bird creature tokens with flying.
• Draw a card for each card your opponents have drawn this turn.

Target permanent becomes a colorless Mountain land until the beginning of your next upkeep.

Creatures you control get +X/+0 and gain first strike until end of turn.

Destroy target creature.

Legacy (You may play this side of this card only from your graveyard. Exile it if it would be put into a graveyard or not resolve.)
Target creature gets -4/-4 until end of turn. When that creature dies this turn, other creatures its controller controls get -1/-1 until end of turn.

Whenever an opponent attacks, exile Last Offer. If you do, target opponent sacrifices an attacking creature and you return another enchantment card from your graveyard to your hand.

Put two +1/+1 counters on target creature. You gain life equal to that creature's power.

Forebode three times, then untap each Omen you control. Until end of turn, if you would draw a card while your library has no cards in it, you win the game instead. (Create three tapped colorless Omen artifact tokens with “{T}, Discard a card, Sacrifice this artifact: Draw a card.”)

Exile the top seven cards of your library. Choose up to one card of each card type and put those cards into your hand.

Until end of turn, creatures you control get +1/+1 and gain trample and poisonous 1. (Whenever one of those creatures deals combat damage to a player, that player gets a poison counter.)

You may cast this spell without paying its mana cost if it targets a creature with power 5 or greater and you control a Swamp and a Mountain.
Last Stop deals 11 damage to target creature. That creature loses indestructible until end of turn.

Up to two target creatures can't block this turn.
Agonize (You may cast this card from your graveyard by putting a -1/-1 counter on a creature you control in addition to paying its other costs. Then exile this card.)

Whenever a nontoken creature you control dies, you may exile it. If you do, create a token that's a copy of it except it is an enchantment. (It still has its abilities, but it's not a creature or other types.)

Target creature gets +X/+0 until end of turn, where X is the number of instant and sorcery cards in your graveyard.

Lava Plume deals 3 damage to any target.
At the beginning of each end step, if you have 5 or less life, you may pay {R} and exile Lava Plume from your graveyard. If you do, it deals 3 damage to any target.

Lava Spill deals 2 damage to any target.
Look at the top three cards of your library. Put one on top and the rest on the bottom in any order.

({T}: Add {B} or {R}.)
Lavatorn Fields enters tapped unless you control a basic Swamp or a basic Mountain.

Counter target spell unless its controller pays {4}. If that spell is countered this way, exile it instead of putting it into its owner's graveyard.
