Search your library for two cards with different names and reveal them. An opponent chooses one. Put the chosen card into your graveyard and the rest into your hand. Then shuffle.

Choose two —
• Target creature you control fights another target creature.
• Exile target artifact.
• Destroy target land. Its controller creates a tapped colorless land token named Lotus Spring with “{T}: Add one mana of any color.”
• Target player returns a land card from their graveyard to their hand.

(Transcend as a sorcery to gain that type and a +1/+1 counter.)
You may play an additional land on each of your turns.
{1}{R}{G}: Demigod — Whenever a land you control enters this turn, it deals 3 damage to up to one target creature or planeswalker.
{6}{R}{G}: God — Until end of turn, lands you control become 3/3 Spirit creatures with indestructible and haste that are still lands. Untap them.

Flying
When Zhu Long enters, if {W}{U}{B}{R}{G} was spent to cast it, untap up to five target lands.
Once during each of your turns, when you cast an instant or sorcery spell, if no more than one mana of each color was spent to cast it, you may copy it. You may choose new targets for the copy.

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}{R}{G}{W}: You may put a creature card from your hand onto the battlefield. It gains haste and vigilance until end of turn. At the beginning of the next end step, return it to your hand unless you're in a renaissance.

[+1]: Each opponent discards a card. If a land card is discarded this way, create a 1/1 colorless Spirit creature token with flying.
[–2]: Until end of turn, creatures you control get +1/+1 and creatures your opponents control get -1/-1.
[–6]: Each opponent chooses up to one permanent they control of each permanent type, then sacrifices the rest.

At the beginning of your end step, if you're horrific, you draw a card and you lose life equal to the number of cards in your hand. (You're horrific as long as you've sacrificed a permanent or discarded a card this turn.)

After a player chooses two or more modes while casting a spell, you may pick one of those modes. That mode is no longer chosen. (That player doesn't pick targets or pay costs related to that mode. If a mode is chosen multiple times, only one instance of that mode is lost.)

[+1]: Search your library for a land card, put it onto the battlefield, untap it, then shuffle. Sacrifice a land.
[–2]: Destroy target noncreature permanent. Its controller may search their library for a basic land card, put that card onto the battlefield, then shuffle.
