When Petal Scatterer enters, create a green Aura enchantment token named Blossom attached to target land. It has enchant land and “Enchanted land has ‘{T}: Add {G}{G}.'”
Petal Scatterer gets +1/+1 for each noncreature, nonland permanent you control.

First strike
When Petal of a Heart enters, if you cast it, reveal up to two permanent cards with mana value 1 from your hand. For each card revealed this way, conjure a duplicate of that card into your hand.

[+1]: You may play an additional land this turn.
[–1]: Discard a card. If you do, return target creature, land or sorcery card from your graveyard to your hand.
[–5]: Create Thrice-Folded Lotus, a colorless Masterpiece artifact token with “{T}: Add three mana of any one color.” and “{3}, {T}: This artifact deals 3 damage to any target.”

Enchant permanent
Enchanted permanent is a colorless Swamp Forest land.
Whenever enchanted permanent becomes tapped, its controller loses 1 life.

Flying
Whenever Phantasmal Owl attacks, it gets +1/+1 until end of turn for each other creature you control with flying.

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's a 1/1 white Spirit creature in addition to its other types and colors.
{2}{B}, Sacrifice a creature: Each opponent loses 1 life and you gain that much life.

When Phantom Threader enters, create a white Aura enchantment token named Spectral Whispers attached to target creature. The token has enchant creature and “Enchanted creature has double strike as long as you control it. Otherwise, it can't attack or block.”

When Phasmopillar enters, search your library for a creature card with mana value 5 or greater, reveal it, put it into your hand, then shuffle. If a creature card with mana value 9 or greater was revealed this way, put two +1/+1 counters on Phasmopillar.

Whenever a source you control deals damage to an opponent this turn, exile the top card of your library. You may play it this turn.

Trample
Phoberos Ragehorn has haste as long as you control another Minotaur.
Whenever Phoberos Ragehorn attacks, each player discards a card.

Flying, haste
Whenever Phoenix of Agonas attacks, you may discard a card. If you do, draw a card.
{4}{R}: Return Phoenix of Agonas from your graveyard to your hand. This ability costs {X} less to activate, where X is your devotion to red. (Each {R} in the mana costs of permanents you control counts toward your devotion to red.)

You may cast instant and sorcery cards from your graveyard. Spend no more than one mana of each color to cast spells this way each turn. If a spell cast this way would be put into your graveyard, exile it instead.

Return X target creature cards with mana value 3 or less from your graveyard to the battlefield, then choose one of them and exile the rest.

Create a token that's a copy of target permanent you control, except it isn't legendary. Then put Picture Perfect on the bottom of its owner's library if you cast it from exile.
Leitmotif (If you cast this spell from your hand, exile it as it resolves. When you next cast a spell that shares a color with this card, you may cast this from exile without paying its mana cost.)

[+1]: Create a 1/1 white Cat creature token with lifelink.
[–1]: When you next activate a nonmana ability of target permanent this turn, copy that ability. You may choose new targets for the copy.
[–7]: Exile up to seven target permanents. Return those cards to the battlefield under their owner's control at the beginning of the next end step.

Archive 2 (As this enters, shuffle the top two cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
{R}{W}: Put a nontoken artifact or creature you own on the bottom of the archived library. Create a token that's a copy of it.

Destroy target creature or planeswalker. That permanent's controller loses 3 life unless that player sacrifices a nonland permanent or discards a card.

Discard your hand, then for each creature you control that dealt combat damage to a player this turn, draw a card and create a Treasure token.
{1}{R}, Tap an untapped Pirate you control, Discard Pieces of Eight: Create a 2/1 black and red Cat Pirate creature token with menace.

Choose one —
• Counter target spell unless its controller pays {X}.
• Counter target spell with mana value X.

Ward—Discard a card. (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player discards a card.)
You have “Ward—Discard a card.”

Whenever Pineblight Caribou enters or attacks, you may have it consume a land. If you do, draw a card and you gain 2 life. (To consume a land, sacrifice a land or exile a land card from your graveyard.)

Flying
Morph {5}{W}{W} (You may cast this card face down as a 2/2 creature for {3}. Turn it face up any time for its morph cost.)
When you turn Pinnacle Seraph face up, destroy all other creatures.

{T}: Target player exiles a card from their graveyard.
{1}, Exile Pinnacle of Purity: Exile all graveyards. Search your library for a basic land card, reveal it, put it into your hand, then shuffle.

When Pious Flutist enters, create an Idol token. (It's an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

When Pious Warden enters, choose one —
• Exile target creature you don't control until Pious Warden leaves the battlefield.
• Destroy target enchantment.
• You gain 5 life.
