Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
Whenever Primal Ruffian attacks, if it has a +1/+1 counter on it, other creatures you control get +1/+1 until end of turn. (If it had no counters on it when it attacked, this ability does not trigger.)

Reach
When Primordial Artisan enters and at the beginning of your upkeep, look at the top card of your library. If it's a permanent card with mana value less than or equal to your devotion to green, you may put it onto the battlefield. (Each {G} in the mana costs of permanents you control counts toward your devotion to green.)

{U}: Primordial Manifestation gets +1/-1 until end of turn.
Whenever Primordial Manifestation deals combat damage to a player, draw a card.

Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)
Flying
Dragon spells you cast have cascade.

When Prismatic Basilisk enters, you may search your library for a permanent card with mana value 1 or less, reveal it, put it into your hand, then shuffle.

When Prismatic Champion enters, create a white Aura enchantment token named Sunward attached to target creature. The token has enchant creature and “Enchanted creature has protection from creatures.”

Enchant land
Whenever enchanted land is tapped for mana, its controller adds an additional one mana of any color that land could produce.

Flying
Whenever Prismatic Scyphozoa attacks or blocks, target player mills three cards.
When Prismatic Scyphozoa dies, create four 1/1 blue Elemental creature tokens with flying.

Defender
Whenever you cast an enchantment, instant, or sorcery spell, scry 1 if it's the first time this ability has resolved this turn. If it's the second time, Prismscale Piranhas can attack this turn as though it didn't have defender. If it's the third time, whenever Prismscale Piranhas deals combat damage to a player this turn, draw a card.

Whenever a Monkey creature you control becomes the target of a spell or ability, you may reveal the top card of your library. If you do, counter that spell or ability if it has the same mana value as the revealed card. (Abilities have a mana value of 0.)

As Pristine Chapel enters, you may pay 3 life. If you don't, it enters tapped.
{T}: Add {W}, {B}, or {G}.

({T}: Add {G}, {U}, or {R}.)
Pristine Dominion enters tapped.

{T}: Add {C}. You gain 1 life.
Pristine Frame gets +2/+2 and has flying as long as you have 25 or more life.

Creatures can't attack you unless their controller pays {2} for each of those creatures.
At the beginning of each opponent's end step, if you didn't lose life this turn, you get a glory counter. (You lose glory counters before life. A player with ten or more glory counters wins the game.)

Once each turn, when one or more artifacts you control deals damage to an opponent, you may exile the top card of your library. You may play that card this turn. The same is true for enchantments, planeswalkers, instant spells, and sorcery spells.

Reveal the top card of your library and put that card into your hand. If it's a permanent card with mana value X or less, instead you may put it onto the battlefield. If you do and fewer than seven permanents have been put onto the battlefield this way, repeat this process. X can't be 0.

Flying
Prodigious Panya has base power and toughness 4/4 during extra turns.

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.)

Profane Emissary gets +2/+2 and has lifelink as long as you control a Demon.
If you would draw a card, you may instead search your library for a Demon card, reveal it, put it into your hand, then shuffle. You lose life equal to that card's mana value.

Flying, lifelink
