Whenever Power of Redemption attacks, choose one —
• Remove all -1/-1 counters from all creatures you control.
• Untap all creatures you control.

Enchant creature
Enchanted creature gets +1/+1 for each other creature on the battlefield that shares a creature type with it.

Tap up to three target creatures.
Compose (Then if you cast this from your hand, exile it and create a Saga token with “r3—You may cast a copy of this card from exile without paying its mana cost.”)

First strike
Whenever a nontoken creature you control leaves the battlefield, you may pay {W}. If you do, create a 1/1 colorless Spirit creature token.

Look at target opponent's hand. You may exile a noncreature, nonland card from it. For as long as that card remains exiled, its owner may cast it. A spell cast this way costs {2} more to cast.
Draw a card.

(Activate each submodule once as a sorcery. When this enters, activate one submodule for free.)
Flash
{2}{W}: Prioritize
Put two +1/+1 counters on target tapped creature.
{2}{U}: Precipitate
Look at the top six cards of your library. Exile one face down, then shuffle. For as long as that card is exiled, you may cast it if it's an instant or has flash.
{1}{W}{U}: Process
Precognition Module gains “Whenever you cast another spell with flash or an instant, surveil 2.”

When Precursor Custodians enters, exile up to one target creature. As long as that card remains exiled, its owner may cast it. A spell cast this way costs {2} more to cast.

Creatures you control get +0/+2 until end of turn. Untap those creatures.

Put a +1/+1 counter on target creature.
Draw a card.

When Presence of the Unknown enters, you may sacrifice a creature. When you do, exile target nonland permanent.
Whenever a creature you control dies, each opponent loses 1 life and you gain 1 life.

Harmony — Exile another target creature until Pretentious Performer leaves the battlefield.
When Pretentious Performer enters, harmonize. (Trigger up to one harmony of one permanent you control.)

{1}, Sacrifice a creature: Each opponent loses 1 life.
Whenever a creature dies, you gain 2 life.

Destroy target creature with power 3 or greater.

Create three 2/2 white Cat creature tokens.
Fuse (You may cast one or both halves of this card from your hand.)

Spells your opponents cast cost {2} more to cast for each card with the same name as that spell in that player's graveyard and for each nonland permanent on the battlefield with the same name as that spell.

Each player can't untap more than one nonbasic land during their untap step.

Distribute a vigilance, trample, first strike, and lifelink counter among up to four target creatures you control, then distribute four +1/+1 counters among those creatures.

Flash
When Priority Paradigm enters, conjure a card named Data-Point into your hand. (It's a sorcery that costs {2} with “Draw a card.”)
The first sorcery spell you cast each turn has flash.

Whenever you cast a spell, you gain 1 life for each of its colors other than white.

Flash
When Prismatic Champion enters, create a white Aura enchantment token named Sunward attached to target creature. The token has enchant creature and “Enchanted creature has protection from creatures.”

Lifelink
Heretic (Whenever you cast a spell that doesn't share a color with this creature, it gets +1/+1 until end of turn.)

Double strike
Concord — Pristine Duelist gets +2/+1 as long as there are four or more card types among permanents you control.

Creatures can't attack you unless their controller pays {2} for each of those creatures.
At the beginning of each opponent's end step, if you didn't lose life this turn, you get a glory counter. (You lose glory counters before life. A player with ten or more glory counters wins the game.)

When Prized Holsteins enters, create a 2/2 white Dwarf creature token.
When Prized Holsteins leaves the battlefield, you gain 2 life.

Surveil 3. Then you gain 3 life and draw three cards. (To surveil 3, look at the top three cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)
Cycling {2} ({2}, Discard this card: Draw a card.)
