First strike
Prevent all damage that would be dealt to creatures you control by sources with greater mana value.
{2}{W}{W}: Create a 1/1 colorless Construct Actor creature token. Put a vigilance counter on it.

At the beginning of your upkeep, each player discards a card. Then if a player has no cards in hand, you may transform Performer of Ambition.

Target player discards two cards. Forebode. (Create a tapped colorless Omen artifact token with “{T}, Discard a card, Sacrifice this artifact: Draw a card.”)

Whenever a creature dies, scry 1.
{2}{U}, Exile a creature card from your graveyard: Draw a card.

{2}{B}, {T}, Sacrifice another creature: Each opponent loses 2 life and you gain 2 life.

When Pestilent Vermin enters, target opponent loses 2 life unless they discard a card.
Whenever you cast a Tale, you may return Pestilent Vermin from your graveyard to your hand.

Whenever another creature you control enters, put a +1/+1 counter on a creature you control.

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.

Whenever a noncreature permanent enters, Petaldiver deals 1 damage to that permanent's controller.

Choose any number of target nonland permanents each controlled by different players. For each of those permanents, return it to its owner's hand. If you returned a permanent you controlled this way, create a 3/3 green Plant Elemental creature token with reach.

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

Enchant creature you control
Enchanted creature has lifelink.
When Phantasmal Possession enters, exile target creature an opponent controls until Phantasmal Possession leaves the battlefield.

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.

Put a +1/+1 counter on each creature you control. If this spell was cast from a graveyard, those creatures gain flying until end of turn.
Flashback {5}{W}{W} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

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.”

Invocation — Whenever you spend four or more mana to cast a spell or activate an ability during your turn, create a 2/2 green Wolf creature token.
{4}{G}{G}{G}: Other creatures you control get +3/+3 and gain haste until end of turn.

Indestructible
As long as your devotion to black and green is less than seven, Pharika isn't a creature.
At the beginning of your upkeep, create a 1/1 green Snake creature token. If Pharika is a creature, create a 1/1 black Snake creature token with deathtouch instead.

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.

Indestructible
As long as your devotion to blue and black is less than seven, Phenax isn't a creature.
Whenever one or more cards are put into your graveyard from your hand or library, you may return one of those cards to your hand. Do this only once each turn.

Enchant creature
When Philosophical Conundrum enters, scry 1.
Enchanted creature can't attack or block.

Lifelink
Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)

Whenever a creature you control dies, draw a card if it had power greater than its base power.

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.)

{2}, {T}, Exile a card from your graveyard: Draw a card.
