When 1-ST Thankless Companion enters the battlefield, draw a card.

You draw two cards and you gain 3 life.
Coalesce {5}{W}{U} (You may cast this from your graveyard for {5}{W}{U}. If you do, put it onto the battlefield as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

Each other Okus planeswalker you control enters the battlefield with two additional loyalty counters on it.
[–2]: Create a 2/2 white Knight creature token with vigilance.

If this spell targets a card that was put into a graveyard from the battlefield this turn, you may pay {W} rather that pay its mana cost, and cast it as though it had flash.
Return target creature card from your graveyard to the battlefield.

Vigilance
Cadence (Whenever you cast a spell, if its mana value is greater than this creature's power, put a +1/+1 counter on this creature.)

Flying

Legendary spells you cast have nonlegendary cascade. (When you cast that spell, exile cards from the top of your library until you exile a nonlegendary nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)

Whenever you cast a noncreature spell, put a +1/+1 counter on Abjuration Savant. It gains flying until end of turn.
When Abjuration Savant dies, you gain life equal to its toughness.

At the beginning of your end step, you may pay {W}. If you do, exile target creature you control, then return that card to the battlefield under your control.

Destroy target creature with power 4 or greater. You gain 2 life.

Exile any number of target cards in exile. (They become new objects that have just been exiled.)
Draw a card.

Flying
Whenever Acabo, the Fabled Falcon attacks, you choose how up to one target creature an opponent controls blocks this turn.

After a player chooses two or more modes while casting a spell, you may pick one of those modes. That mode is no longer chosen. (That player doesn't pick targets or pay costs related to that mode. If a mode is chosen multiple times, only one instance of that mode is lost.)

Exile target creature or planeswalker and up to one target card from its controller's graveyard.

Enchant creature
Enchanted creature gets +2/+2. Other creatures you control get +1/+1.

Flying
{2}{W}, Exile a non-Spirit creature card from your graveyard: Create a 1/1 white Spirit creature token with flying.

Invigorate 5. (Choose a creature with the least power among creatures you control and put five +1/+1 counters on it.)

At the beginning of your upkeep, you may reveal a creature card from your hand. If you do, create a token that's a copy of it, except it's 1/1 and is an artifact in addition to its other types.

Lifelink
Converge — When Adapted Explorer enters the battlefield, it deals X damage to up to one target tapped creature, where X is the number of colors of mana spent to cast it.

Search your library for a creature card with mana value 3 or less, put it onto the battlefield, then shuffle. It gains haste until end of turn. Return it to your hand at the beginning of the end step.

Flying
Whenever another creature enters the battlefield under your control, Adavene, Dean of the Arts deals 1 damage to each opponent.
Whenever a creature you control deals combat damage to a player, you may exile it, then return it to the battlefield.

Whenever Adept Lieutenant attacks, 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.”)
{1}, Sacrifice an Idol: Put a +1/+1 counter on Adept Lieutenant.

Flash
When Adiran Distractor enters the battlefield, return up to one target creature you control and up to one target creature you don't control to their owners' hands.

Choose one —
• Destroy target artifact.
• Destroy target enchantment.
• Counter target spell unless its controller pays {1}.

Extort (Whenever you cast a spell, you may pay {W/B}. If you do, each opponent loses 1 life and you gain that much life.)
Creatures can't attack you or planeswalkers you control unless their controller pays {2} for each of those creatures.
