As an instant or sorcery spell not cast from exile resolves, exile it instead of putting it anywhere else.
Once each turn, you may cast a card exiled with Eidetic Memory.

{1}, {T}: Draw a card, then exile a card from your hand face down.
You may look at cards exiled with Ekebram's Archive.
{4}, {T}, Sacrifice Ekebram's Archive: Return all cards exiled with Ekebram's Archive to their owner's hand.

{T}: Add {C}.
{2}, {T}: Add {C} for each Desert you control.

Exile target permanent, then return that card to the battlefield under its owner's control.

Whenever a nontoken creature you control dies, you may put a +1/+1 counter on target creature. If you do, that creature's controller loses 1 life.

Whenever Eldan Jackson deals combat damage, return target permanent card with mana value 3 or less from your graveyard to the battlefield.

Whenever Hatsuo attacks, if you control three or more attacking creatures, attacking creatures you control gain first strike until end of turn.
Inspired — Whenever Hatsuo becomes untapped, create a 1/1 white Warrior creature token. It gains haste and attacks this turn if able.

Whenever Chian becomes the target of a spell or ability you control, create a 2/2 blue Drake creature token with flying. This ability triggers only once each turn.

At the beginning of your upkeep, look at the top four cards of your library. You may reveal a storied card from among them and put it into your hand. Put the rest on the bottom of your library in any order. (Enchantment and legendary cards are storied.)

Whenever one or more creatures you control deal combat damage to a player or planeswalker, create a Clue token.
{G}{U}, Sacrifice a Clue: Put a +1/+1 counter on target creature. Proliferate.

You may reveal an Avatar or planeswalker card you own from outside the game and put it into your hand.

The next creature spell you cast this turn can be cast as though it had flash. When that creature enters this turn, it gains lifelink until end of turn.

Flash
Creatures you control that have entered this turn get +1/+1 and have haste and first strike.

Counter target spell, activated ability, or triggered ability unless its controller pays {X}. (Mana abilities can't be targeted.)

Choose one —
• Each opponent sacrifices a nonlegendary creature.
• Each opponent sacrifices a legendary creature or planeswalker.

{1}{R}, {T}, Sacrifice an artifact: Elise, Maktali Prodigy deals 2 damage to any target.
{1}{U}, {T}, Sacrifice an artifact: Return target nonland permanent to its owner's hand.
{3}{U}{R}, {T}, Sacrifice three artifacts: Discard your hand, then draw seven cards.

At the beginning of your upkeep, you may search your library for a permanent card with mana value 1 or less, put it onto the battlefield, then shuffle.

Elrayin, the Manaroot enters tapped.
Whenever you tap another land for mana, put a creation counter on Elrayin.
{T}, Remove ten creation counters from Elrayin and sacrifice it: Untap all lands target player controls.

Whenever you cast an instant or sorcery spell, exile cards from the top of your library until you exile an instant or sorcery card. You may cast that card until you exile another card with this ability.

If a permanent would deal damage to Elusive Fatecrafter, instead prevent that damage and exchange control of Elusive Fatecrafter and that permanent.

Flash
{U}, Put Elusive Hunter into its owner's library second from the top: Counter up to one target spell unless its controller pays {2}.

Whenever Elvish Wayfinder enters or attacks, reveal the top four cards of your library. You may put a land card that doesn't share a name with a land you control into your hand. Put the rest on the bottom of your library in any order.

At the beginning of combat on your turn, choose one —
• Embodiment of Nature gains haste and hexproof until your next turn.
• Embodiment of Nature gains vigilance and indestructible until your next turn.
• Embodiment of Nature gets +2/+2 and gains trample until your next turn.

Creatures and nonbasic lands your opponents control enter tapped.
Morph {3}{W}{W} (You may cast this card face down as a 2/2 creature for {3}. Turn it face up any time for its morph cost.)
When you turn Embodiment of Order face up, it becomes a 4/4 white Angel creature with flying.

Whenever you discard a card this turn, add {B}. Then you may cast that card. (You still pay its costs.)
