Destroy target nonland permanent. If it had flying, put a flying counter on a creature you control. Do the same for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance.

Each player sacrifices a creature with the highest power among creatures they control and a creature with the lowest power among creatures they control.

At the beginning of each upkeep, choose one that hasn't been chosen —
• Exile target tapped nonland permanent.
• Draw two cards, then discard a card.
• Return up to two target permanent cards from your graveyard to your hand.
• Exile Take the City, then return it to the battlefield under your control.

Basic lands you control have all basic land types.
Augmented — Whenever you cast an instant or sorcery spell, if you've spent {W}{U}{B}{R}{G} to cast spells this turn, copy it. You may choose new targets for the copy.

Creatures you control with flying get +1/+1.
At the beginning of combat on your turn, target creature you control soars. (Put a flying counter on it. If it already has flying, put a +1/+1 counter on it instead.)

Flying
As Tal, Locus Sentry enters, choose a noncreature, nonland card type.
Spells of the chosen type cost {1} more to cast.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I, II — Create a Treasure token. (It's an artifact with “{T}, Sacrifice this artifact: Add one mana of any color.”)
III — For each color, return up to one target creature card of that color from your graveyard to your hand.
​

Transcend (Activate as a sorcery to gain the next type and a +1/+1 counter.)
Flying
Tamaak the Arid Swarm can only transcend if you've sacrificed a permanent this turn.
{B}{G}: Demon — Create two 1/1 black Insect creature tokens with flying.
{X}{B}{G}: Elder — Destroy each other nonland, nontoken permanent with mana value X or less.

Choose two —
• Each opponent sacrifices a nontoken creature.
• Each opponent sacrifices a nontoken artifact or enchantment.
• Each opponent sacrifices a nontoken planeswalker or battle.
• Return a permanent card from a graveyard that was put there from the battlefield this turn to the battlefield under your control.

Flying, trample
If a creature card would be put into an opponent's graveyard from anywhere, exile it with a soul counter on it instead.
Whenever Tamaak's Devourer deals combat damage to a player, put a creature card exiled with a soul counter on it onto the battlefield under your control.

Menace
Whenever Tamaak's Mouth attacks, defending player sacrifices a nonland permanent.

Flying
Whenever a player taps a land for mana, return that land to its owner's hand unless they pay 1 life.
At the beginning of each end step, if an opponent controls no tapped lands, transform Tamaak, Drought of Life.

Trample
{3}{B}{G}, Discard two cards: Return Tammil and Sulei, the Guides and another target creature card from your graveyard to the battlefield tapped.

Until end of turn, target creature gets +2/+2, then an additional +2/+2 for each card and token merged with it.
