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.

Flying
Whenever a creature you control attacks alone, choose one —
• Exile target creature with power less than that creature's power.
• Put two +1/+1 counters on that creature.
• That creature gains first strike and lifelink until end of turn. Untap it.

Trample
Resolute — {G}: Prowling Agamid gets +3/+3 until end of turn. Activate only once each turn and only if Prowling Agamid's power is greater than its base power.

Flying
When Pyre Apostle enters, discard your hand, then draw three cards.
Madness {3}{R} (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)

You may change any targets of target spell that targets you or a permanent you control. If you don't, counter that spell.

Flash
When Qililia's Scavenger enters, look at the top six cards of your library. You may put a Merfolk card with lesser mana value from among them onto the battlefield. Put the rest on the bottom of your library in a random order.
Other Merfolk you control get +1/+1.

Whenever you cast an instant or sorcery spell, you may conjure two duplicates of it into your main library, then shuffle. Then if there are two or more cards in your graveyard that share a name with that spell, copy it. You may choose new targets for the copy.

Enchant creature
Enchanted creature gets +1/+2 and has flying.

As long as you control two or more other Pirates, Ragavan has haste.
Whenever one or more Pirates you control deal combat damage to a player, create a tapped Treasure token.

Haste
When Rainy Night Lovers enters, look at the top four cards of your library. You may cast a red instant or sorcery spell with mana value 1 from among them without paying its mana cost. Then put the rest on the bottom of your library in any order.

Pressure {1}{G} (You may cast this spell for its pressure cost if seven or more cards are in your graveyard.)
Search your library for three basic land cards and reveal them. Put one onto the battlefield tapped, one into your hand, the rest into your graveyard, then shuffle.

Menace
Discard a card: Target artifact creature you control salvages Rappel Liner. Activate only if Rappel Liner is in your graveyard and only as a sorcery. (Exile this card until that creature leaves the battlefield. When that creature deals combat damage to a player, return a card it salvaged to your hand.)

Menace
When Rattled Bones dies, forebode. (Create a tapped colorless Omen artifact token with “{T}, Discard a card, Sacrifice this artifact: Draw a card.”)

When Raving Brigand enters, forebode. (Create a tapped colorless Omen artifact token with “{T}, Discard a card, Sacrifice this artifact: Draw a card.”)
Whenever you sacrifice an Omen, target player mills three cards.

Flying, ward {2}
Whenever Realm Crossers deals combat damage to a player, create a blue enchantment token named Tambo with “At the beginning of your upkeep, draw a card if you control a Scout.”

Choose two or four —
• Each opponent sacrifices an artifact.
• Create a 1/1 red Warrior creature token.
• Creatures you control get +1/+0 and gain trample and haste until end of turn.
• 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}: Target creature gains haste until end of turn.
{1}{R}, {T}, Sacrifice a Human: Create a token that's a copy of the sacrificed creature, except it's a 3/2 colorless Horror. It gains haste until end of turn. Activate only as a sorcery.

When Recruits of the Demeter enters, draw a card if you control another Pirate.

First strike
Redeye Commando's power is equal to twice the number of artifacts you control.
Redeye Commando attacks each turn if able.

Cycling {2} ({2}, Discard this card: Draw a card.)

Slipstream (This creature can't be blocked as long as only creatures with slipstream are attacking.)
As long as you control three or more artifacts, Regal Seasnake has vigilance. (Attacking doesn't cause it to tap.)

Target instant or sorcery card in your graveyard gains flashback until end of turn. Its flashback cost is equal to its mana cost.
Flashback—{R}, Discard a card. (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Mill three cards. Return a card from among the milled cards to your hand. Then shuffle three cards from graveyards into their owners' libraries.
