When Feralborn Druid enters, create two 2/2 green Wolf creature tokens.
Feralborn Druid gets +1/+1 for each Wolf you control.

Haste
Menace (This creature can't be blocked except by two or more creatures.)
{4}{R}{R}: Ferocious Desert-Hunter gets +X/+0 until end of turn, where X is its power.

Ferocious Flame deals 2 damage to any target. If you control a creature with power 4 or greater, it deals 4 damage instead.

Ferried Stagecoach can't be blocked as long as another creature is attacking.
Whenever Ferried Stagecoach deals combat damage to a player, each player flips a coin. Each opponent that loses the flip discards a card, and each player on your team that wins the flip draws a card.

Whenever Ferris, the Sapphire Storm or another creature you control enters, each opponent mills X cards, where X is that creature's power.

Fertile Steppe enters tapped unless you have 15 or less life.
{T}: Add {G} or {W}.

{1}, {T}, Move a -1/-1 counter from another creature onto Fervent Arbiter: Exile target creature you don't control until Fervent Arbiter leaves the battlefield.

Flying
You may exert Fervent Igmel as it attacks. When you do, add {R}{R}{R}{R}. Until end of turn, you don't lose this mana as steps and phases end. (An exerted creature won't untap during your next untap step.)

When Festering Shipwreck enters, create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)
At the beginning of each player's upkeep, that player sacrifices a nonland permanent.

At the beginning of your upkeep, mill a card.
{1}, Exile three cards from your graveyard: Put a -1/-1 counter on target creature.

Choose one —
• Festival Sabotage deals 2 damage to any target.
• Audition for red. (Create a 1/1 Construct Actor creature token, a Warrior Role giving 3/2 and trample, or a Wizard Role giving 2/2 and prowess. Roles replace older ones.)

Enchant creature you control
When Festive Euphoria enters, you gain life and draw cards equal to enchanted creature's power.
Enchanted creature can't be blocked by creatures with power 2 or less.

When Fetching Gancanagh dies, draw a card. At the beginning of the next end step, up to one target creature you control becomes a copy of Fetching Gancanagh.

{T}: Add {C}.
{T}, Pay 1 life: Add {G} or {U}.

Whenever another nontoken creature you control dies, create a 1/1 black Rat creature token with “This creature can't block” if this is the first time this ability has resolved this turn. Otherwise, Ffion, Famine Warcaller deals 1 damage to each player.

When Fidelity of the Pure dies, create a 1/1 green and white Elk Spirit creature token.
Revive {2}{W} ({2}{W}, Exile this card from your graveyard: Create a token that's a copy of it except it has no mana cost. Revive only as a sorcery.)

When Field Technician enters, you may search your library for an artifact card, reveal it, then shuffle and put that card on top of it.
Artifact creatures you control get +1/+1.

You may play lands from your graveyard.
Whenever a land you control enters, create a 1/1 white Peasant creature token.

This spell costs {1} less to cast for each card you've drawn this turn.
Fiery Burst deals 3 damage divided as you choose among any number of targets.

Fiery Erasure deals 3 damage to target creature or planeswalker. If that permanent would die this turn, exile it instead.

Target opponent chooses up to one creature. Destroy the rest.

Fiery Temper deals 3 damage to any target.
Madness {R} (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)

Flash
When Fiery Truthseeker enters, you may cast target instant or sorcery card with mana value 3 or less from your graveyard without paying its mana cost. If that spell would be put into your graveyard, exile it instead.

Destroy target nonland permanent.
Monument {W}{B} (You may cast this transformed from your graveyard for its monument cost. Exile it if it would leave the battlefield or not resolve.)

(As an Encounter enters, choose an opponent to protect it. You and others can attack it. When defense counters are removed, create a 0/0 Army token if you don't control one, then put that many +1/+1 counters on a Army you control.)
Whenever a creature you control attacks Figments of the Muktann, create a token that's a copy of that creature that's tapped and attacking the player protecting Figments of the Muktann. Sacrifice the token at the beginning of the next end step.
