When you turn Pinnacle Seraph face up, destroy all other creatures.

{3}{W}{W}: Detain target nonland permanent. (Until your next turn, that permanent can't attack or block and its activated abilities can't be activated.)

Stinging Swordfish has first strike as long as it's attacking.
When Stinging Swordfish dies, create an Equipment enchantment artifact token named Fish Sword with “Equipped creature gets +3/+1,” “Equipped creature has first strike as long as it's attacking,” and equip {2}. You may attach that token to a creature you control.

Reach
As Celestial Principality enters, choose a number.
Noncreature spells with mana value equal to the chosen number can't be cast.

• Destroy target artifact or enchantment.
• Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

{T}: Choose artifact or enchantment. Target nonland permanent becomes the chosen type in addition to its other types until end of turn.
Civilized — At the beginning of your end step, if you control an artifact, a creature, and an enchantment, put a +1/+1 counter on target creature you control.
