Search your library for two land cards and reveal them. If you attacked this turn, put them onto the battlefield tapped. Otherwise, put them into your hand. Then shuffle.

Choose one —
• Forge Trick deals 3 damage to target creature.
• Target creature gets +3/+0 until end of turn.

Counter target spell unless its controller pays {4}.

Equipped creature has first strike.
{R}: Equipped creature gets +1/+0 until end of turn.
Equip {2}

Reveal the bottom card of your library. You may put it on top of your library. Target creature gets -0/-X until end of turn, where X is that card's mana value.

{T}: Add {C}.
{1}, {T}, Sacrifice a creature: Create a 1/1 colorless Spirit creature token.

Search your library for a creature card, an instant card and a sorcery card and reveal them. Put one of those cards into your hand, exile the rest, then shuffle.

Codex — Majestic Dominion; Pristine Dominion; Verdant Dominion; Stalwart Dominion; Primal Dominion; Rugged Dominion; Into the Woods. (As this enters, conjure its contents into a shuffled face-up additional library.)
Before you explore this library, you may put a card from the codex's library on top of it.
{3}{G}: Target creature you control explores.

{T}, Pay 1 life: Add {R} or {G}.
{1}, {T}, Sacrifice Forgotten Shrine: Investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw 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 you draw a card from the archived library, each opponent mills two cards.

{T}: Add {C}. Exile a card from your graveyard.
{3}: Until end of turn, Forgotten Temple becomes an X/X creature, where X is the number of cards exiled by it. It's still a land.
As long as a creature card with flying is exiled by Forgotten Temple, it has flying. The same is true for first strike, double strike, deathtouch, experience, haste, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance.

When Forlorn Farmhand dies, create a 1/1 colorless Spirit creature token.

Exile all creatures with power 4 or greater.

Flying
Mark (Whenever this creature attacks, mark target creature until end of turn.)
Whenever a marked creature dies, you gain 2 life.

Forsaken Sunseeker gets +1/+1 and has flying as long as it's not your turn.

When Forserval enters, creatures you control get +1/+1 and gain haste until end of turn.

Equipped creature gets +0/+2 and has flying.
Equip {2}

Spells with mana value 2 or less cost {1} more to cast.
Spells with mana value 4 or greater cost {1} less to cast.

Enchant creature
Enchanted creature has frenzy 3. (Whenever that creature attacks and isn't blocked, it gets +3/+0 until end of turn.)

Flying
Whenever Frenzied Sylph attacks or blocks, you may pay {R}. If you do, it gets +3/+0 until end of turn. Exile it at the beginning of the next end step.

As an additional cost to cast this spell, you may sacrifice a creature.
Create a 1/1 green Insect creature token. If you sacrificed a creature to cast this spell, create three of those tokens instead.

Whenever one or more cards leave your graveyard for the first time each turn, each player loses 1 life and you draw a card.

Whenever a creature you control enters, if its mana value is greater than the number of bloom counters on From a Seed, put a bloom counter on From a Seed.
Creatures you control get +1/+1 for each bloom counter on From a Seed.

All creatures get -2/-2 until end of turn.

Up to two target lands you control become 1/1 black Bear creatures with deathtouch. They're still lands. (Then exile this card. You may cast the creature later from exile.)
