Fahrib's Tongue can't be blocked by creatures with two or more creature types.
Whenever Fahrib's Tongue deals combat damage to a player, that player loses 1 life for each creature that dealt damage to them this turn.

Target creature gets -9/-0 until end of 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.”)

Lifelink
If you would gain life, you may put that many +1/+1 counters on another creature you control instead.

Exile the top two cards of your library. Until the end of your next turn, you may play those cards. (If you cast a spell this way, you still pay its costs. You can play a land this way only if you have an available land play remaining.)

Enchant creature
Embody (Enchanted creature is a copy of this card except for its types.)
As long as Legend of the Devout is tapped, creatures you control have lifelink.

Eternal Duneborn enters tapped.
Foresight — Whenever you draw your second card each turn, return Eternal Duneborn from your graveyard to your hand.

Trample
{1}{G}: Brackish Kelpie gets +2/+2 until end of turn. Activate only once each turn.

Rouse 2. Target permanent gains trample until end of turn if it's a creature. (Distribute two +1/+1 counters among permanents you control. If they aren't creatures, tap them and they become 0/0 creatures in addition to their other types.)

Up to two target creatures you control each get +2/+0 and gain first strike and haste until end of turn.
Orchestrate—Tap an untapped red and white creature you control or an untapped red creature you control and untapped white creature you control. (You may exile this card from your hand anytime you could cast a sorcery for its orchestrate cost. When you next resolve a spell, you may cast this from exile without paying its mana cost.)

Flying, deathtouch

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I, II — Audition for green. (Create a 1/1 Construct Actor creature token, a Scout Role giving 2/3 and vigilance, or a Warrior Role giving 3/2 and trample. Roles replace older ones.)
III — Creatures you control get +1/+0 and gain trample until end of turn.
​

Careless Violence deals 2 damage to each creature. If a creature dealt damage this way would die this turn, exile it instead.

Choose one —
• Counter target spell unless its controller pays {2}.
• Tap target creature. It doesn't untap during its controller's next untap step.

If you cast this spell from exile, it deals 7 damage to target creature. Otherwise, return Fortunous Flames to your hand, then reveal a card from your hand at random.
Prophecy {R} (Once each turn, you may exile a card with prophecy as you reveal it. When you do, you may cast it for its prophecy cost as long as it's exiled.)

Cinder Arrows deals 3 damage to target creature.

{5}, {T}, Tap an untapped creature you control: Put target card from your or a teammate's graveyard on top of its owner's library.

When Seeker's Guardian enters, reveal the top card of your library.

Vigilance
Revive {3}{G} ({3}{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.)

When The Moon Rises enters, exile all opponent's graveyards.
At the beginning of your upkeep, each opponent loses 1 life.

Choose one —
• Destroy target artifact or enchantment with mana value 3 or less.
• You gain 3 life. Draw a card.

When this creature enters, create a 2/2 black Zombie creature token. That token seeks secrets and gains haste until end of turn. (Give it that Oath Aura. Fulfill it by attacking with it and two or more other creatures to draw a card.)

Whenever Aukashi, Electric Legacy enters or equipped creature dies, attach Aukashi to a creature you control.
Whenever equipped creature deals damage to a permanent or player, Aukashi deals 2 damage to that permanent or player.
Equipped creature has double strike as long as a creature you controlled died this turn.
Equip {2}

When Deputy Gibem enters, post a bounty on each creature and each planeswalker. (Put a bounty counter on those permanents. Each of them have “When this permanent dies, each opponent draws a card” as long as it has a bounty counter on it.)

Shuffle your library, then exile cards from the top until you exile an artifact card. You may put that card into your hand. Shuffle the rest back into your library.
