Exile the top five cards of your library. You may play one of them from exile this turn.

Enchant opponent
At the beginning of your end step, if you've gained 3 or more life this turn, choose one. If you've gained 7 or more life this turn choose any number instead.
• Enchanted player sacrifices a creature.
• Enchanted player discards two cards.
• Enchanted player loses 4 life.

Flying, deathtouch
Whenever an opponent loses life for the first time each turn, that player loses 1 life and you gain 1 life.

When Onward to War enters, draw a card, then choose a card name.
Whenever one or more creatures you control with the chosen name attack, look at the top four cards of your library. Put a creature or enchantment card with mana value 3 or less from among them into your hand. Put the rest on the bottom of your library in any order.

Your opponents skip their upkeep steps.
At the beginning of your first upkeep each turn, you get an additional upkeep step after this step.

Archive 3 (As this enters, shuffle the top three cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever you draw a card from the archived library, you exile up to one target creature. Return that card to the battlefield under its owner's control at the beginning of the next end step.

Creatures you control get +1/+1 until end of turn.
Inscribe {2}{W} ({2}{W}: Exile this card from your hand inscribed on a creature you control. Whenever that creature attacks, its controller may cast a copy of the inscribed card without paying its mana cost. Inscribe only as a sorcery.)

Exile up to one target creature or planeswalker with mana value 3 or less. Then if this spell was foretold, target opponent chooses a creature or planeswalker they control. You gain control of that permanent.
Foretell {3}{U}{U}{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.)

Vigilance
Wanderlust — When Telarine Zenitheer dies, if you control four or more differently named lands, create two 1/1 Scout creature tokens that are all colors.

When Scribal Puppeteer enters, create two 1/1 black Puppet creature tokens with “At the beginning of your upkeep, you lose 1 life.”

Target creature can't block this turn.
Inscribe {1}{R} ({1}{R}: Exile this card from your hand inscribed on a creature you control. Whenever that creature attacks, its controller may cast a copy of the inscribed card without paying its mana cost. Inscribe only as a sorcery.)

Ghost Sloop can't be blocked.
Crew 4 (Tap any number of creatures you control with total power 4 or greater: This Vehicle becomes an artifact creature until end of turn.)
Exile a creature card from your graveyard: Ghost Sloop becomes an artifact creature until end of turn.

Vigilance
Once each turn, when you cast an instant, sorcery, or Elemental spell, you may put a +1/+1 counter on Ignited Vanguard.

Enchant creature
Enchanted creature gets +1/+0 and has trample and reach.

Once each turn, when another creature is returned to your hand from the battlefield, you may put a +1/+1 counter on Esalia's Courser.
{1}{G}: Esalia's Courser gains trample and vigilance until end of turn.

Bjarndyr Bruiser gets +2/+2 as long as it's embattled. (A creature is embattled if it has a counter on it or has a permanent you control attached to it.)

Trample
Whenever you cast a noncreature spell, crystallize. If you create a Treasure this way, Heartforge Savant deals 1 damage to you for each Treasure you've created this turn. (Put a +1/+1 counter on a creature you control or create a Treasure.)

Create three 2/1 red and white Fox creature tokens.

Flash
When Binding Stones enters, exile target creature with power 3 or less until Binding Stones leaves the battlefield.

Refuse to Submit deals 3 damage to any target. If that target is an attacking creature, it deals 5 damage instead.

Deathtouch
Sacrifice a creature: Target player mills two cards.

Menace (This creature can't be blocked except by two or more creatures.)

Reach
As long as you control an artifact or an enchantment, Heron's Grace Patrol gets +1/+1 and has vigilance.
{2}{G}{W}, {T}: Mill three cards. You may return a permanent card milled this way to your hand.

When Archivist Heretic enters, you lose 1 life, then investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)

When Mystic Seer enters, each player may scry 1.
{2}{U}: Draw a card, then discard a card.
