msem-instigator

Destroy all monocolored creatures.

Slipstream (This creature can't be blocked as long as only creatures with slipstream are attacking.)
As long as you control three or more artifacts, Regal Seasnake has vigilance. (Attacking doesn't cause it to tap.)

Choose two —
• You gain 3 life.
• Tap target creature.
• Put a +1/+1 counter on target creature.

Flash
When Reinforced Platemail enters the battlefield, you may attach it to target creature you control.
Equipped creature you control gets +1/+2.
Equip {3}

Harmony — Destroy target artifact or enchantment.
When Rejoicing Aristocrats enters the battlefield, harmonize. (Trigger up to one harmony of one permanent you control.)

Target player sacrifices an attacking creature. You gain life equal to that creature's power.

Vigilance
Disgraced 1 (This enters with a -1/-1 counter. Whenever it deals combat damage to a player, remove all -1/-1 counters from it.)

Choose a creature. Exile the rest.

Exile target artifact, enchantment, or tapped creature.

Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter on it and it becomes renowned.)
When Renegade Spiritualist becomes renowned, create a 1/1 green Spirit creature token.

When Renili, Telenian Weaponist enters the battlefield, you may exile another target creature until Renili leaves the battlefield.
When Renili leaves the battlefield, put a +1/+1 counter on each creature you control.

Whenever another creature you control is dealt damage, put a +1/+1 counter on it. If you do, upgrade Renowned Healer. (Give it one of the listed counters it doesn't already have. The damaged creature must survive to get the counter.)
• +1/+1
• Flying
• Lifelink

Tap up to two target creatures.
Draw a card.

Flash
If a player would conjure a card, they instead conjure a card named Data-Point. (It's a sorcery that costs {2} with “Draw a card.”.)
If a player would copy a spell or cast a copy, they copy the card named Data-Point instead of anything else.

This spell costs {2} less to cast as long as you've sacrificed an Idol this turn.

Creatures you control get +2/+1 until end of turn.
Cycling {1}{W} ({1}{W}, Discard this card: Draw a card.)

Purge. You gain 3 life. (To purge, exile two cards that share a type from graveyards. If you do, draw a card.)

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

At the beginning of each end step, you may exile target creature card with mana value X or less from your graveyard, where X is the amount of life you gained this turn. If you do, create a token that's a copy of it.

Lifelink
Whenever another creature you control with a counter on it dies, return it to its owner's hand. If that creature was an Avatar, return it to the battlefield under your control instead.

If this spell was orchestrated, up to one target permanent you control gains indestructible until end of turn. Choose a nonland permanent type. Destroy all permanents of the chosen type.
Orchestrate {2}{W}{W} (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.)

Exile the bottom four cards of your library. Return a creature or enchantment card from among them to your hand. You gain life equal to its mana value.

[+1]: Creatures you control get +1/+0 and gain respawn until end of turn. (When one dies, if it attacked this turn, return it to its owner's hand.)
[0]: You get an emblem with “Whenever a creature you control attacks, you gain 1 life.”
[–5]: Until end of turn, Revela becomes a legendary Human Cleric Avatar creature with lifelink, indestructible, and “This creature's power and toughness are each equal to your life total.”

{1}{W}: Target creature you control gets +0/+1 until end of turn and assigns combat damage equal to its toughness rather than its power this turn. When that creature deals combat damage to a player this turn, transform Reversal Medic.
