Leonardo Borazio

Over all his works a dark smoke hung and wrapped itself about the sides of Orthanc.

Saruman, the White Hand

Whenever you cast a noncreature spell, amass Orcs X, where X is that spell's mana value. (Put X +1/+1 counters on an Army you control. It's also an Orc. If you don't control an Army, create a 0/0 black Orc Army creature token first.)
Goblins and Orcs you control have ward {2}.

Tom, Bert, and William

{1}, Sacrifice another creature: Draw cards equal to the sacrificed creature's power, then discard a card.
When Tom, Bert, and William die, if they were a creature, return them to the battlefield. They're an artifact. (They're no longer a creature.)

To leave the Fire Nation required incredible trust. They had that in Jeong Jeong.

Jeong Jeong's Deserters

When this creature enters, put a +1/+1 counter on target creature.

"Stand your ground! The Earth King must be protected!"

Earth Kingdom Protectors

Vigilance
Sacrifice this creature: Another target Ally you control gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy it.)

"I am...a legend now. The Fire Nation will, for generations, tell stories about the great Zhao who darkened the moon."

Blood Moon

Synth Infiltrator

Improvise (Your artifacts can help cast this spell. Each artifact you tap after you're done activating mana abilities pays for {1}.)
You may have this creature enter as a copy of any creature on the battlefield, except it's a Synth artifact creature in addition to its other types.

Robobrain War Mind

Robobrain War Mind's power is equal to the number of cards in your hand.
When this creature enters, you get an amount of {E} (energy counters) equal to the number of artifact creatures you control.
Whenever this creature attacks, you may pay {E}{E}{E}. If you do, draw a card.

Preston Garvey, Minuteman

At the beginning of combat on your turn, create a green Aura enchantment token named Settlement attached to up to one target land you control. It has enchant land and "Enchanted land has '{T}: Add one mana of any color.'"
Whenever Preston Garvey attacks, untap each enchanted permanent you control.

The difference between surviving and living is joy.

Panharmonicon

If an artifact or creature entering causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

Éomer, King of Rohan

Double strike
Éomer enters with a +1/+1 counter on it for each other Human you control.
When Éomer enters, target player becomes the monarch. Éomer deals damage equal to its power to any target.

It raised the whip, and the thongs whined and cracked. Fire came from its nostrils. But Gandalf stood firm.

You Cannot Pass!

Destroy target creature that blocked or was blocked by a legendary creature this turn.

Sail into the West

Will of the council — Starting with you, each player votes for return or embark. If return gets more votes, each player returns up to two cards from their graveyard to their hand, then you exile Sail into the West. If embark gets more votes or the vote is tied, each player may discard their hand and draw seven cards.

Gandalf the White

Flash
You may cast legendary spells and artifact spells as though they had flash.
If a legendary permanent or an artifact entering or leaving the battlefield causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

"It's a dangerous business, Frodo, going out of your door. You step into the Road, and if you don't keep your feet, there is no knowing where you might be swept off to."
—Bilbo

Farseek

Search your library for a Plains, Island, Swamp, or Mountain card, put it onto the battlefield tapped, then shuffle.
