Enchant permanent
When Tempted by Lotuses enters, enchanted permanent's owner creates three colorless artifact tokens named Lotus Petal with “{T}, Sacrifice this artifact: Add one mana of any color.”
You control enchanted permanent.

At the beginning of your upkeep, exile the top card of each of your libraries.
Put X cards exiled with Possibility Matrix on the bottom of their owner's library: You may cast a nonland card exiled with Possibility Matrix with mana value X or less without paying its mana cost.

Until end of turn, noncreature lands you control become 3/3 Elemental creatures with haste and trample.
Orchestrate {1}{G} (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.)

Vigilance
{2}{G}: Danuri Phalanx gets +2/+2 until end of turn. Activate only once each turn.

Counter target spell. If you control a Wizard, scry 2. (To scry 2, look at the top two cards of your library, then put any number of them on the bottom of your library and the rest on top in any order.)

Target creature can't block this turn. (Then exile this card. You may cast the creature later from exile.)

Put target nonland permanent on top of its owner's library.

Flying
When Djinni of Whispers enters, untap up to three Islands.

{W}{U}, {T}: Target creature gets +2/+2 and gains flying until end of turn.
{U}{B}, {T}: Target player mills three cards.
{B}{R}, {T}: Monolith of Ages deals 3 damage to any target.
{R}{G}, {T}: Target creature gets +4/+2 and gains trample until end of turn.
{G}{W}, {T}: Populate. (Create a token that's a copy of a creature token you control.)

{T}: Add {C}.
{2}, {T}, Sacrifice Failing Port: Draw a card.

Flying (This creature can't be blocked except by creatures with flying or reach.)
When Iridescent Familiar enters, if you control another creature with flying, draw a card.

Draw a card.
Whenever Seek Guidance is put into your graveyard from your hand or library, scry 2. (This doesn't include being cast.)

Persist (When this creature dies, if it had no -1/-1 counters on it, return it to the battlefield under its owner's control with a -1/-1 counter on it.)

Draw two cards, then discard a card.
Whenever you cast an instant or sorcery spell, if Spirit Script is in your graveyard, you may have it become a copy of that spell until end of turn.

Germinate three times. (To germinate, put a +1/+1 counter on a creature or create a 1/1 green Saproling creature token.)

Thriving Bluff enters tapped.
As Thriving Bluff enters, choose a color other than red.
{T}: Add {R} or one mana of the chosen color.

{3}, {T}: Put a +1/+1 counter on target creature you control. Activate only as a sorcery.

Hexproof from mana value 3 or less
{W}: Rhysta of the Roses gains lifelink until end of turn.
{B}: Rhysta of the Roses gains menace until end of turn.

Search your library for a basic land card, put it onto the battlefield tapped, then shuffle. Then if you control seven or fewer lands, return Evergrowth to your hand.

Surging Lightning deals 2 damage to target creature or planeswalker. If you've cast another spell this turn, it deals 4 damage instead.

Siphon (Each -1/-1 counter you put on your creatures up to their remaining toughness while casting this pays for {1}.)
Costly Ambush deals damage equal to the greatest power among creatures you control to target creature or planeswalker.

When Opulent Proprietor enters, you may search your library and/or graveyard for an Aura, Aurashaper, Equipment, or Vehicle card, reveal it, and put it into your hand. If you search your library this way, shuffle.

Enchant creature
When Tomb Robber's Grit enters, investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)
Enchanted creature gets +1/+1.

Golden age (If you cast an instant or sorcery spell, activated a nonmana ability, and attacked this turn, enter a renaissance for this game.)
{2}{G}{W}: Create an Idol token. Prevent all damage that would be dealt to and dealt by target creature this turn.
At the beginning of your end step, if you're in a renaissance and you control ten or more Idols, you win the game.

Lands you control have hexproof.
{2}{G}{U}: Rouse 2. (Distribute two +1/+1 counters among permanents you control. If they aren't creatures, tap them and they become 0/0 creatures in addition to their other types.)
