Discovery — Creatures you control with defender can attack as though they didn't have defender.

Whenever you cast a noncreature spell, Hutao's Wardens deals 2 damage to each opponent. Then if that spell was an enchantment, scry 2.

Lifelink
When Hyctaleon's Vanguard enters, look at the top six cards of your library. You may put a Soldier card with lesser mana value from among them onto the battlefield. Put the rest on the bottom of your library in a random order.
Other Soldiers you control get +1/+1.

Creatures you control have “{T}: Add {C} or one mana of any of this creature's colors.”
Attain {5}{G} ({5}{G}: Transform this. Spend at least three colors of mana to activate this, and only as a sorcery.)

Harness (You may tap a creature you control as you cast this spell. If you do, reduce this spell's mana cost by that creature's power.)
Search target opponent's library for a creature or planeswalker card and put it onto the battlefield under your control. That player shuffles.

Exile all creature cards from target player's graveyard. For each creature card exiled this way, search that player's library for any number of cards with the same name as that card and exile them. Then that player shuffles.

{T}: Add {C}.
{3}{U}: Until end of turn, I's Observatory becomes a 1/4 creature. It's still a land. It has menace if {B} was spent to activate this ability, has first strike if {R} was spent, and assigns combat damage equal to its toughness rather than its power if {G} was spent.

Archive 3 (As this enters, shuffle the top three cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever you cast a spell from your hand, you may cast a card from the archived library with a lesser mana value without paying its mana cost.

[+1]: Create a token that's a copy of another target permanent. Exile that token at the beginning of your next upkeep.
[–3]: If it's not an extra turn, you take an extra turn after this one, then skip your next turn that's not an extra turn.
[–6]: Until end of turn, planeswalkers become copies of I, Queen of Eons, except they aren't legendary. Destroy all nonland, non-I permanents.

{1}{W}: Artifact creatures you control get +1/+1 until end of turn. Activate only once each turn.

This spell costs {1} less to cast and can't be countered if it targets a cursed opponent.
Target opponent mills eight cards. Exile up to two nonland cards milled this way. Until the end of your next turn, you may cast those cards and mana of any type can be spent to cast those spells.

Cast this spell only before attackers are declared.
Target creature you control gets +X/+0 until end of turn and gains haste until end of turn, where X is its power. At the beginning of the next end step, sacrifice that creature if it attacked this turn.

Whenever Icepeak Phantasm becomes the target of a spell or ability, an opponent may pay {2}. If they do, sacrifice it.

Enchant opponent
Cards in enchanted player's graveyard lose all abilities and all names.
If enchanted player would mill one or more cards, they instead mill that many cards plus X, where X is the number of Curses attached to them.

(Activate each submodule once as a sorcery. When this enters, activate one submodule for free.)
{R}{R}{R}: Bold
Any player may have Identity Module deal 5 damage to them. If no one does, draw three cards.
{R}{R}{R}: Brash
Identity Module deals 3 damage to any target.
{R}{R}{R}: Burning
Identity Module gains “Players can't gain life” and “At the beginning of each player's upkeep, Identity Module deals 2 damage to that player.”

Idyllic Oasis enters tapped unless you control a Plains.
{T}: Add {G} or {U}.

Concord — At the beginning of your upkeep, if there are four or more card types among permanents you control, you gain 1 life and create a 1/1 blue Jellyfish enchantment creature token with slipstream. (It can't be blocked as long as only creatures with slipstream are attacking.)

Search your library for an enchantment card, reveal it, put it into your hand, then shuffle.

Augmented — When you cast If Memory Serves, if you've spent {W}{U}{B}{R}{G} to cast spells this turn, copy it twice. You may choose new targets for the copies.
Return target permanent card with mana value 3 or less from your graveyard to the battlefield. Exile If Memory Serves.

At the beginning of combat on your turn, gain control of another target permanent until end of turn. Untap that permanent. It gains haste until end of turn.
Fleeting {2}{R}{R} (You may cast this spell for its fleeting cost. If you do, sacrifice it at the beginning of the next end step.)

Once each turn, when you gain life, you may exile the top card of your library. You may play that card this turn.
Whenever you cast your second spell each turn, Ignition Engine deals 2 damage to target player or planeswalker.

Ignition Point deals 3 damage to any target.
The next card you cast this turn can be cast as though it has flash.

As an additional cost to cast this spell, pay X life.
Ignition Ritual deals X damage to each creature and each planeswalker.

You get a fuse counter, then Ignition Sequence deals X damage to any target, where X is 2 plus the number of fuse counters you have.

Flash
