{T}, Sacrifice Fortune Charm: Look at the top two cards of your library, then put them back in any order. Draw a card.

Civilized — Whenever Founding Hero attacks, if you control an artifact, a creature, and an enchantment, Founding Hero gains double strike until end of turn.

When Fox of the Sunset Legion enters, create two 1/1 white Fox Spirit creature tokens.

{T}, Sacrifice an artifact or creature: Fracking Factory deals 2 damage to each opponent. Activate only as a sorcery.

{T}: Add {C}.
{T}, Pay 1 life: Add one mana of any color. Activate only during an opponent's turn.

Target creature gets -1/-1 until end of turn. If that creature is tapped, it gets -3/-3 until end of turn instead.

Lifelink
Frenzied Watchkeeper enters with six -1/-1 counters on it.
At the beginning of each end step, if an opponent lost life this turn, remove a -1/-1 counter from Frenzied Watchkeeper.

At the beginning of your end step, choose one at random —
• Create a tapped Treasure token.
• Forebode. (Create a tapped colorless Omen artifact token with “{T}, Discard a card, Sacrifice this artifact: Draw a card.”)
• Arm target creature you control. (Create a colorless Equipment artifact token with “Equipped creature gets +1/+0” and equip {2}, then attach it to that creature.)

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
Whenever you cast a noncreature spell, Frilled Drakeling gains menace until end of turn.

Whenever a creature you control enters for the first time each turn, you may sacrifice it. If you do, exile cards from the top of your library until you exile a creature card. Put that card onto the battlefield.

At the beginning of your end step, untap all lands you control. You may put three +1/+1 counters on target land you control. If you do, that land becomes a 0/0 Treefolk creature with haste that's still a land.

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.)

When Frontier Savior enters, return up to two target creature cards with mana value 3 or less from your graveyard to the battlefield.

When Frost Walker becomes the target of a spell or ability, sacrifice it.

({T}: Add {U} or {R}.)
Frostfire Geysers enters tapped unless you control a basic Island or a basic Mountain.

Frostpoint Caldera enters tapped unless you control a basic land.
{T}: Add {U} or {R}.

This spell costs {1} less to cast for each creature card in your graveyard.

Untap all permanents you control.
Coalesce {5}{G}{U} (You may cast this from your graveyard for {5}{G}{U}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)
{G}{U}: Untap Fulfill Twisted Dreams.

At the beginning of your draw step, draw an additional card. If you control three or more artifacts, draw two additional cards instead.
At the beginning of your end step, discard your hand.

[+1]: Draw a card, then discard a card.
[–2]: Fulmen, Aether Prodigy deals 2 damage divided as you choose among one or two targets. Draw a card.
[–6]: Whenever you cast an instant or sorcery spell this turn, copy it. You may choose new targets for the copy.

{U}{R}, {T}: Fulmen deals 1 damage to target creature. When a creature dealt damage this way dies this turn, draw a card.
Whenever you cast an instant or sorcery spell, if you cast another instant or sorcery spell this turn, exile Fulmen, then return him to the battlefield transformed under his owner's control. He deals 3 damage to each creature.

[+2]: Draw two cards, then discard two cards unless you discard an instant or sorcery card.
[–3]: Reveal any number of cards from your hand. Fulmen deals damage to any target equal to the number of instant and sorcery cards revealed.
[–9]: Search each player's library for up to one instant card and one sorcery card. Cast those cards without paying their mana costs. Then each player shuffles.

({T}: Add {B} or {G}.)
