Prowess
Whenever Prodigal Spark is dealt damage, it deals that much damage to any target.

When Prodigious Telemancer enters, you may draw a card, then discard a card.
Whenever you cast an instant or sorcery spell, you may aetherize target creature you control. (To aetherize, create a token that's a copy of it, then exile that token.)

Revive {6}{B} ({6}{B}, 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.)

At the beginning of your upkeep, you may exile a card from your hand with a knowledge counter on it. If you do, draw a card. Then you may have Professor Adelia become a copy of any permanent card you own in exile with a knowledge counter on it, except it has this ability.

Whenever Professor's Assistant becomes tapped, add {R}. Until end of turn, you don't lose this mana as steps and phases end.

Prophecy {G} (Once each turn, you may exile a card with prophecy as you reveal it. When you do, you may cast it for its prophecy cost as long as it's exiled.)

Once each turn, when an Aura is attached to Prop Custodian or you cast a spell that targets it, you may audition for white. (Create a 1/1 Construct Actor creature token, a Scout Role giving 2/3 and vigilance, or a Cleric Role giving 2/2 and lifelink. Roles replace older ones.)

Whenever you cast a noncreature spell, you may put a progress counter on Propaganda Division.
[progress 2-4] At the beginning of your end step, each opponent loses 1 life and you gain that much life.
[progress 5+] At the beginning of your end step, each opponent loses 1 life for each Project you control and you gain that much life.

Whenever equipped creature deals combat damage to a player, put a +1/+1 counter on it, then proliferate. (You choose any number of permanents and/or players with counters on them, then give each another kind of a counter already there.)
Equip {2}

Foretell {X}{B} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)
Target creature gets -X/-X until end of turn. If this spell was foretold, you gain X life.

{1}{W}, {T}, Sacrifice Prophet of Pacifism: Prevent all damage that would be dealt to players this turn.
Persist (When this creature dies, if it had no -1/-1 counters on it, return it to the battlefield under its owner's control with a -1/-1 counter on it.)

Whenever equipped creature attacks, exile the top card of your library. Equipped creature gets +X/+0 until end of turn, where X is the mana value of that card. Until end of turn, you may play that card.

Other creatures you control get +0/+1.

{4}{G}{W}, Sacrifice Protect the Farm: Creatures you control get +2/+2 until end of turn.

As Protect the Treasure enters, choose offense or defense.
Whenever an artifact you control enters for the first time each turn,
• Offense — Protect the Treasure deals 2 damage to each opponent.
• Defense — Add {R}{R}.

Choose two or four —
• Prove Worthy has lifelink and can't be countered.
• Prove Worthy deals 3 damage to target player or planeswalker.
• Prove Worthy deals 3 damage to target creature or planeswalker.
• Conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

{T}, Pay 1 life: Add {G} or {W}.
{2}, {T}, Sacrifice Provincial Hamlet and another permanent: Draw a card. Activate only during your turn.

When Provincial Loyalty enters, put a vigilance counter on each of up to two target creatures you control.
At the beginning of combat on your turn, permutate. (You may remove a counter from a creature you control. If you do, put two +1/+1 counters on a different creature you control.)

At the beginning of your end step, if you control two or more tapped creatures, you may exile target creature. If you do, return that card to the battlefield under its owner's control.

Target player reveals their hand. You choose a nonland card from it. That player discards that card. You lose 1 life.
Investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)
