Enchant creature
As Hunter's Distinction enters, you may tap enchanted creature if it's untapped. When you do, put three -1/-1 counters on target creature with flying.
Enchanted creature gets +3/+2 and has reach.

{1}{G}{G}, Discard a card: Destroy target artifact or enchantment.
At the beginning of your end step, if twelve or more cards are in your graveyard, create two 3/3 green Beast creature tokens.

Reach
When a creature you control scavenges Huolin Ranger, put a reach counter on that creature.
Scavenge {3}{G} ({3}{G}, Exile this card from your graveyard: Put a number of +1/+1 counters equal to this card's power on target creature. Scavenge only as a sorcery.)

[+1]: Prevent all damage that would be dealt to up to one other target permanent until your next turn.
[–2]: Target creature gets +3/+3 until your next turn.
[–3]: Untap all nonland permanents you control.

Target creature you control becomes a white Bear with base power and toughness 3/5, hexproof, and double strike until end of turn. Whenever it deals combat damage to a player this turn, draw a card.

Archive 6 (As this enters, shuffle the top six cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
You may play Aura and Equipment cards from the archived library, and play those spells as though they had flash.

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

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.)

Hymn of Fury deals 1 damage to each creature, then each creature you control gains haste and double strike until end of turn.

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.

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.

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.

You may have Icefang Wurm assign its combat damage as though it weren't blocked.
{4}{G}{G}: Monstrosity 3. (If this creature isn't monstrous, put three +1/+1 counters on it and it becomes monstrous.)

Target creature gets -2/-1 and gains winnow until end of turn. (Damage dealt to it also causes its controller to lose that much life.)

Menace
When Icilica's Icestrider enters, choose one —
• Draw a card if you own a card in exile.
• Target player discards a card if that player owns a card in exile.

When Ideologize enters, exile target creature an opponent controls and each other permanent with the same name that player controls. When Ideologize is no longer on the battlefield, return a card exiled with it to the battlefield under its owner's control.

Whenever you cast a spell, you may cast a spell from your hand with lesser mana value without paying its mana cost.
You can't cast more than one spell of each card type each turn.

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
When Idleglen Instructor enters, draw a card, then discard a card.

Each nontoken land you control has all activated abilities of each other land on the battlefield.
When Idyll leaves the battlefield, until the end of your next turn, you gain “Each nontoken land you control has all activated abilities of each other land on the battlefield.”

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

When Iekin's Portal enters, look at the top five cards of your library. Put one into your hand and the rest into your graveyard.
{1}{U}{U}: Transform Iekin's Portal. Activate only if your fealty to Islands is five or greater.

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.

{G}{U}{R}, Discard a card named Ifram, God of Chaos: Ifram gains indestructible and becomes a God creature in addition to its other types.
Whenever Ifram enters or attacks, choose target non-God permanent. Its owner shuffles it into their library, then its controller reveals the top card of their library. If it's a permanent card, they put it onto the battlefield.

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.
