Each player chooses a legendary permanent from among the nonland permanents they control, then sacrifices the rest.

Draw two cards.
Rerun (If you cast this from your hand, exile it as it resolves. Whenever a creature you control dies, you may cast this card from exile without paying its mana cost.)

Choose one —
• Draw seven cards.
• End the turn. (Exile all spells and abilities, including this. The player whose turn it is discards down to their max hand size. Damage wears off, and “this turn” and “until end of turn” effects end.)

This spell costs {1} less to cast for each storied permanent you control. (Enchantments and legendary permanents are storied.)
Destroy all nonland, nonstoried permanents.

As an additional cost to cast this spell, sacrifice a creature.
Exile target creature.

When Final Symphony enters, exile another target nonland permanent until Final Symphony leaves the battlefield.
When Final Symphony leaves the battlefield, draw a card.

As an additional cost to cast this spell, sacrifice a permanent.
Exile the top two cards of your library. Until the end of your next turn, you may play those cards.

Exile the top card of your library. You may cast it. (Then exile this card. You may play the land later from exile.)

Cycling {3} ({3}, Discard this card: Draw a card.)

{R}, Sacrifice Firebelly Toad: It deals 3 damage to target player or planeswalker.

When Fireheart Channeler dies, you may exile it. If you do, put a blaze counter on target land without a blaze counter on it. As long as that land has a blaze counter on it, it has “At the beginning of your upkeep, this land deals 1 damage to you.” (The land continues to burn after Fireheart Channeler has left the battlefield.)

Firehearth Halls enters tapped unless you control a basic Mountain.
{T}: Add {R}.
{R}{R}: Firehearth Halls becomes a 1/1 red Dwarf Warrior creature with double strike until end of turn. It's still a land.

When Flailing Terror becomes monstrous, target opponent sacrifices two creatures.

When Flamboyant Inventor enters, create a tapped colorless Powercell artifact token with “{T}: Add {C}.”
