Reveal the top thirteen cards of your library. For each permanent type, you may put a card of that type revealed this way into your hand. Put the rest into your graveyard. (The permanent types are creature, land, artifact, enchantment and planeswalker.)

Whenever War Priest of Bahet deals combat damage to a player, purge. (Exile two cards that share a type from graveyards. If you do, draw a card.)

Whenever a nontoken creature enters the battlefield under your control, you may scry 1. (To scry 1, look at the top card of your library. You may put that card on the bottom of your library.)

Exile the bottom card of your library, a card from your hand, and a card you own from outside the game. Put them in a face down pile, shuffle that pile, then manifest those cards. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

Lifelink

• That player discards a card.
• Put a +1/+1 counter on Adversary Ancestor.

{W}{B}{G}, Discard a card named Bahet, God of Destruction: Bahet gains indestructible and becomes a God creature in addition to its other types.
Whenever Bahet enters the battlefield or attacks, each player chooses a number of lands they control equal to the number of lands controlled by the player who controls the fewest, then sacrifices the rest. Players discard cards and sacrifice non-God creatures the same way.

Destroy target creature. Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

[+1]: Discard a card. If you do, up to one target player gains 5 life.
[–3]: Discard a card. You draw X cards and you lose X life, where X is that card's mana value.
[–7]: Exile your hand, then put all cards from your graveyard into your hand and all cards exiled this way into your graveyard.

As an additional cost to cast this spell, discard your hand.
Purge four times, then you gain 1 life for each card in exile. (Exile two cards that share a type from graveyards. If you do, draw a card.)

[+1]: Return up to one target Aura card from a graveyard or on the battlefield to its owner's hand.
[–2]: Sacrifice an enchantment. If you do, return target enchantment card from your graveyard to the battlefield.

When Chimera Graft dies, manifest the bottom card of your library. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

Trial 4 (As you cast this spell, an opponent of your choice may pay 4 life. If they don't, they fail the trial.)
Target player sacrifices two noncreature permanents if they failed the trial.

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

Destroy target creature. End of the Road deals damage equal to that creature's power to that creature's controller or a planeswalker that player controls.

Enchant creature
When Ethereal Fervor enters the battlefield, adjudicate. (Create a white Aura enchantment token with enchant creature and “Sacrifice this token: Untap enchanted creature” attached to target creature.)
Enchanted creature gets +1/+0 for each Aura attached to it, has first strike, and attacks each combat if able.

Draw three cards.

Whenever an Aura enters the battlefield under your control, untap Fuming Lawmaker.
{1}, {T}: For each opponent, Fuming Lawmaker deals 1 damage to that player or a planeswalker they control. Scry 1.

{B}{G}{U}, Discard a card named Gusma, God of Creation: Gusma gains indestructible and becomes a God creature in addition to its other types.
Whenever Gusma enters the battlefield or attacks, add {B}{G}{U} and draw a card. You don't lose this mana as steps, phases, and turns end.

Flying
Whenever Hand of Genesis deals combat damage to a player, manifest the bottom card of your library. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

[+1]: Add {G}{U}{R}. Spend this mana only to cast creature spells.
[–2]: Reveal the top card of your library. If it's a creature card that costs less than the last spell you cast this turn, you may put it onto the battlefield. Otherwise, draw a card.
[–7]: Target creature becomes a legendary 20/20 green creature named Illusion of Kaur with hexproof and trample until end of turn.

When Holy War enters the battlefield, create three 1/1 white Cleric creature tokens.
Creature tokens you control have first strike and lifelink.

{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 the battlefield 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.

Whenever Instability Elemental enters the battlefield or you draw a card except during your draw step, target creature gets +1/+1 until end of turn.
