Flying, vigilance
If a nonland permanent entering the battlefield would cause a triggered ability of a permanent you control to trigger, you may have that ability trigger an additional time. If you do, each opponent copies that ability and may choose new targets for the copies.

{2}{U}{B}, Sacrifice a creature: Return target creature card from your graveyard to the battlefield with a finality counter on it. It gains myriad. (Whenever it attacks, for each opponent other than defending player, you may put a token that's a copy of this creature onto the battlefield tapped and attacking that player or a planeswalker they control. Exile the tokens at end of combat.)

Menace
Whenever Margarete or another creature you control dies, up to one target creature you control cackles. (Put a menace counter on it. If it already has menace, it deals 1 damage to each opponent instead.)
Once each turn, when Margarete or another creature you control with menace dies, you may torment each opponent. (They lose 3 life unless they discard a card or sacrifice a nonland permanent.)

Flying, trample
At the beginning of combat on your turn, goad all creatures with power 3 or less. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)
Whenever a creature deals combat damage to an opponent, put a +1/+1 counter on it.

Vigilance
Creatures you control with a +1/+1 counter on them have mentor. (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)
Creatures you control with no +1/+1 counters on them have training. (Whenever this creature attacks with another creature with greater power, put a +1/+1 counter on this creature.)

Whenever you gain life, amass Zombies 1. (Put a +1/+1 counter on an Army you control. It's also a Zombie. If you don't control one, create a 0/0 black Zombie Army creature token first.)
If you would gain life except for the first time each turn, instead each opponent loses 1 life. (If multiple sources would cause you to gain life at the same time, choose one to be first.)

Ward—Pay 2 life. (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays 2 life.)
You may cast sorcery spells as though they had flash.
Whenever you cast a sorcery spell, Daiju, Lightning-Draw gets +2/+0 and gains first strike until end of turn.

Permanent cards in your graveyard have The Undercity Amalgam's Adventure.
Once during each of your turns, you may cast an Adventure spell from your graveyard.

Exile two target cards from your graveyard. If they share a card type, draw a card. (Then exile this card. You may cast the creature later from exile.)

First strike, haste
Whenever Lothaire attacks, create a 0/0 colorless Reflection creature token that's tapped and attacking. Creatures you control get +1/+1 until end of turn.
{2}{R}{W}: Put a +1/+1 counter on each creature you control.

The Unshakable Kian enters with three wish counters on him.
Remove a wish counter from Kian: Choose one. Activate only as a sorcery and only once each turn.
• Kian gains hexproof and trample until your next turn.
• Tap up to three target nonland permanents and put a stun counter on each of them.
• If you have fewer than four cards in hand, draw cards equal to the difference.

[0]: Choose up to one target creature. You may put two +1/+1 counters on it, a +1/+1 counter on it and a loyalty counter on Aoia, Monarch of Beauty, or two loyalty counters on Aoia.
[–2]: Exile target creature, then return it to the battlefield. For each kind of counter on it before it left, put that many of that kind of counter on it.
[–9]: You get an emblem with “If an effect would put one or more counters on a permanent you control, it puts five times that many of those counters on that permanent instead.”
Aoia can be your commander.

Haste, prowess
Whenever you cast a noncreature spell, journey. (To journey, exile the top card of your library face up. Whenever a creature you control deals combat damage to an opponent, put a journeyed card you own into your hand.)

First strike
At the beginning of your end step, each opponent that lost life this turn loses 1 life and discards a card. You gain life equal to the life lost this way, then draw a card for each land card discarded this way.

When Fel Alston, Halfway Queen enters, return target creature card from your graveyard to the battlefield. Then exile that creature unless Fel Alston was cast for its escape cost.
Escape—{1}{W}{U}{B}, Sacrifice two creatures. (You may cast this card from your graveyard for its escape cost.)

Lifelink, first strike
You may cast creature spells from your graveyard if their mana value is less than or equal to the amount of life you have gained this turn. Whenever you cast a creature spell this way, it enters with a finality counter on it.

Vigilance
Whenever another creature you control attacks, put a +1/+1 counter on it if it has less than 4 power. Otherwise, it gains first strike and trample until end of turn.

Whenever another nontoken creature you control dies, you may exile it. If you do, create a token that's a copy of it, except it has base power and toughness 1/1. If that creature had power 4 or greater, create two of those tokens instead.

When Shadowbinder Touka enters or attacks, exile up to one target creature card from a graveyard.
You may play creature cards exiled with Touka.
Sacrifice another creature: Add two mana in any combination of colors. You can't spend this mana to cast spells from your hand. If this mana is spent to cast a creature spell, that creature enters with a finality counter on it.

Flying, ward {2}
Whenever you cast a noncreature spell, choose up to one target creature. If that spell's mana value is greater than that creature's power, put +1/+1 counters on it equal to the difference.

Once each turn, if a triggered ability of another legendary permanent you control would trigger, you may have it trigger an additional time.

{T}: Add one mana of any color in your commander's color identity.

When Chamber of Reflections enters, draw a card, then choose a legendary card name.
Permanents you control with the chosen name have hexproof and the “legend rule” doesn't apply to them.

Equipped creature has haste.
Sacrifice Cinderblade: Equipped creature gains +2/+2 until end of turn.
Equip {1}

{X}, {T}: Reveal the top card of your library. If its mana value is X or less, you may play it without paying its mana cost. Otherwise, put it into your hand. X can't be 0.
