Reach
When Extolled Arachstruct enters, mill two cards. When you do, choose one —
• Each opponent sacrifices a creature with power less than the number of cards in your graveyard.
• Each opponent sacrifices a creature with power greater than the number of cards in your graveyard.

You may exert Extoller of Effort as it attacks. (An exerted creature won't untap during your next untap step.)
Whenever you exert a creature, create a 1/1 white Human creature token.

Choose one —
• Target opponent reveals their hand. You may choose a creature, enchantment, or planeswalker card from it. That player discards that card.
• Target opponent sacrifices an enchantment.

When Extraction Mercenary enters, if you attacked this turn, crystallize. (Put a +1/+1 counter on a creature you control or create a Treasure.)
{4}{R}{R}: Extraction Mercenary deals 3 damage to any target.

When Extracurricular Studies enters, search target opponent's library for a card and exile it. Then that player shuffles.
You may play cards exiled by Extracurricular Studies and you may spend mana as though it was mana of any type to cast them. When you do, return Extracurricular Studies to its owner's hand.

Gain control of target nonland permanent until end of turn. Untap it. It gains haste until end of turn.

Choose one or both —
• Counter target spell.
• Exile target permanent you control, then return it to the battlefield under your control.

Choose one —
• The next spell you cast this turn has flash and can't be countered.
• Target creature gets +2/+0 and gains haste until end of turn.
• Target creature gets +1/+0 and gains first strike until end of turn.

Stampede — Whenever Exuberant Hunter and a creature with greater power attack, draw a card.

Eureka! (At the beginning of each end step, you get a research counter if you cast a spell this turn. Then if you have eight or more research counters, remove them and create a Masterpiece token of your choice.)
At the beginning of your first end step each turn, you get an additional end step after this step.

{2}, {T}: Tap target creature. This ability costs {2} less to activate if you control an enchantment.

Art of war — At the beginning of your end step, if Exultant Oni dealt damage to an opponent this turn, create an Idol token. (It's an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

Reach, trample
Revive {4}{G} ({4}{G}, 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.)

Your opponents play with their hands revealed.
At the beginning of your end step, choose a card name.

Exile target spell or nonland permanent. That card's owner casts it without paying its mana cost at the beginning of the next turn's upkeep.

Vigilance
Players can't untap more than two lands during their untap steps.

Pressure {X}{U}{U} (You may cast this spell for its pressure cost if seven or more cards are in your graveyard.)
Look at the top card of your library. You may put that card into your graveyard.
Draw a card. If this spell was cast for its pressure cost, draw X cards instead.

When Eyes in Orbit enters, you may exile another target permanent you control. Return that card to the battlefield under your control at the beginning of the next end step.

At the beginning of your upkeep, each player loses 3 life unless they sacrifice a creature.
Sacrifice a creature: Fateseal 1. (Look at the top one cards of an opponent's library, then put any number on the bottom and the rest on top in any order.)

When Eyes of the Maghbri enters, if you control a creature token, create a 2/2 black Hound creature token.

Trample
Noncreature spells cost an additional “Put a noncreature permanent you both own and control on top of your library” to cast.

When Fabled Chishou enters, create a token that's a copy of it, except it doesn't have this ability.
At the beginning of each end step, if Fabled Chishou isn't in a pack, sacrifice it. (Two or more creatures you control with equal power are in a pack.)

Unveil {3}{G}{W} ({3}{G}{W}: Transform this. Unveil only as a sorcery.)

When Fables of the Bold enters, draw a card.
