Look at the top two cards of your library. Put one of them into your hand and the rest into your graveyard.
Rerun (If you cast this from your hand, exile it as it resolves. Whenever a creature you control dies, you may cast this card from exile without paying its mana cost.)

Tap up to two target creatures.
Coalesce {5}{W}{W} (You may cast this from your graveyard for {5}{W}{W}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)
Heavens Claim Their Due enters tapped.

When Blessing of Roya enters or whenever you cast a spell from a graveyard, you gain 5 life and you mill five cards. Then you may put a card from your graveyard on the bottom of your library.

Escalate {2} (Pay this cost for each mode chosen beyond the first.)
Choose one or more —

Flying, lifelink
Creatures entering or leaving the battlefield don't cause abilities to trigger unless that creature is in a pack. (Two or more creatures a player controls with equal power are in a pack.)

When Hisana-no-Oni enters, gain control of target creature until Hisana-no-Oni leaves the battlefield.

Whenever you make first contact, create a 1/1 white Bird creature token with flying. (You make first contact the first time each turn you cast a spell with a name not in your graveyard or control already.)
Whenever three or more creatures you control deal combat damage to a player, create a token that's a copy of another target permanent you control.

Antu, Sun Spirit can't attack or block unless you control ten or more permanents.
As long as it's your turn, other creatures you control get +X/+0 and have haste, where X is the amount of life you've gained this turn.
When Antu dies or is put into exile from the battlefield, you may put him into his owner's library third from the top.

(As an Encounter enters, choose an opponent to protect it. You and others can attack it. When defense counters are removed, create a 0/0 Army token if you don't control one, then put that many +1/+1 counters on a Army you control.)
