msem-instigator

Menace
Art of war — At the beginning of your end step, if Hashiro's Infiltrator dealt damage to an opponent this turn, that player discards a card.

Once during each of your turns, you may cast an instant, sorcery, or enchantment spell from your graveyard that targets a creature you control.

Flying
{1}{W}, {T}: Tap target creature.

({T}: Add {R}, {W}, or {B}.)
Desolate Dominion enters tapped.

Menace
{1}{B}, Exile another three cards from your graveyard: Return Determined Explorer from your graveyard to your hand.

Whenever a creature you control becomes the target of a spell or ability, counter it unless its controller pays {1}. Whenever they do, put a +1/+1 counter on Brushcover Elf. (This includes your spells and abilities.)

Whenever you cast a spell, harmonize twice. (To harmonize, trigger up to one harmony of a permanent you control.)
Harmony — Yita, Almgrove Prodigy gains your choice of flying, first strike, vigilance, lifelink, hexproof, or haste until end of turn.

Choose one —
• Destroy target nonland permanent with mana value less than or equal to the number of card types among cards in your graveyard.
• Return to the battlefield target creature card from your graveyard with mana value less than or equal to the number of card types among permanents you control.

Enchant opponent
Whenever a creature enters under enchanted player's control, that player loses 1 life and you gain 1 life.

Untap all other Elves you control during each other player's untap step.
You may cast spells as though they had flash.

Reach
Erratic (When this creature dies, reveal the top four cards of your library. Put a creature card that costs less than this revealed this way onto the battlefield and the rest on the bottom of your library in any order.)
When Angelbane Spider enters, destroy target creature with flying.

Hexproof
Whenever an opponent casts a noncreature spell, put a +1/+1 counter on Spellbane Vulpine.

Choose two —
• Exile the top two cards of your library. You may play them until the end of your next turn.
• Add {R}{R}.
• Creatures you control get +1/+0 until end of turn.
• Flamecaller's Command deals 1 damage to each creature you don't control.

Flying, prowess
When Bound Watcher enters, conjure a card named Data-Point into your hand. (It's a sorcery that costs {2} with “Draw a card.”)

Return target permanent to its owner's hand.
Coalesce {7}{U} (You may cast this from your graveyard for {7}{U}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

Flying
When Cloudheath Sentinel enters, return target artifact card with mana value 2 or less from your graveyard to the battlefield.

Double strike
Art of war — At the beginning of your end step, if Kogane's Swordmaster dealt damage to an opponent this turn, put a +1/+1 counter on it.

Flash
When Dreamnapper enters, another target creature phases out until Dreamnapper leaves the battlefield. (Treat it and anything attached to it as though they don't exist as long as it's phased out.)

Macabre Effigy enters with three charge counters on it.
{3}, {T}, Remove a charge counter from Macabre Effigy: Create a 2/2 black Zombie creature token. Activate only as a sorcery.

Play with the top card of your library revealed.
You may cast creature spells from the top of your library.
You may pay {W}{U}{B}{R}{G} rather than pay the mana cost for creature spells you cast.

Whenever you put one or more -1/-1 counters on a creature, put that many charge counters on Cycle of Scars.
Remove three charge counters from Cycle of Scars: Copy target instant or sorcery spell you control. You may choose new targets for the copy.

Reach
When Primordial Artisan enters or attacks, look at the top card of your library. If it's a permanent card with mana value less than or equal to your devotion to green, you may put it onto the battlefield. (Each {G} in the mana costs of permanents you control counts toward your devotion to green.)

[+1]: Tap up to one target creature. Azun, Sheriff of Daisite deals 1 damage to each opponent.
[–1]: Exile another target nonland permanent until Azun, Sheriff of Daisite leaves the battlefield.
[–7]: Detain each permanent target opponent controls. (Until your next turn, those permanents can't attack or block and their activated abilities can't be activated.)

Enchant creature
Enchanted creature gets +2/+2 and has flying.

You draw two cards, lose 2 life, and create a Gold token. (It's an artifact with “Sacrifice this artifact: Add one mana of any color.”)
