Flash
Prowess
When Ella enters, create two 1/1 blue Wizard creature tokens with prowess.
Whenever you cast a noncreature spell, you may sacrifice a creature. If you do, copy that spell. You may choose new targets for the copy.

{U}{R}, {T}: Fulmen deals 1 damage to target creature. When a creature dealt damage this way dies this turn, draw a card.
Whenever you cast an instant or sorcery spell, if you cast another instant or sorcery spell this turn, exile Fulmen, then return him to the battlefield transformed under his owner's control. He deals 3 damage to each creature.

[+2]: Draw two cards, then discard two cards unless you discard an instant or sorcery card.
[–3]: Reveal any number of cards from your hand. Fulmen deals damage to any target equal to the number of instant and sorcery cards revealed.
[–9]: Search each player's library for up to one instant card and one sorcery card. Cast those cards without paying their mana costs. Then each player shuffles.

[+2]: Scry 2, then you may draw a card. If you don't, Liactru Stormheart deals 2 damage to any target.
[–4]: Create a 4/4 blue and red Elemental creature token. It gains flying, vigilance, and haste until end of turn.
[–10]: For each player, create a token that's a copy of target permanent that player controls. You get an emblem with “Permanents you control have hexproof.”

If you would draw your first card each turn, instead draw two cards, then discard a card.
Whenever you draw an even numbered card in a turn, put a +1/+1 counter on Saraf, Tuned Disciple. (The second, fourth, sixth, etc.)

At the beginning of each player's upkeep, sacrifice Hayuan, the Misjudged if that player controls a creature with power 2 or less.
When Hayuan dies, create X Idol tokens, where X is the number of creatures you control. (They're artifacts with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

Indestructible
As long as your devotion to black and green is less than seven, Pharika isn't a creature.
At the beginning of your upkeep, create a 1/1 green Snake creature token. If Pharika is a creature, create a 1/1 black Snake creature token with deathtouch instead.

{X}, {T}, Sacrifice an artifact: Exile target artifact card in your graveyard with mana value X. Create a token that's a copy of it. Activate only as a sorcery.

Indestructible
Battalion — Whenever Rallios, Heir to the Evil One and at least two other creatures attack, creatures you control get +1/+0 and gain double strike until end of turn.

Untap all other Elves you control during each other player's untap step.
You may cast spells as though they had flash.

Hexproof
Whenever an opponent casts a spell or draws a card, draw a card.

This spell can't be countered.
Flying
When Aunor, Dragonsire or another Dragon you control enters, untap target land. That land becomes a 5/5 Dragon creature with flying and haste in addition to its other types.

Wildcast — When Ivier, Soul of the Woods enters, return target monocolored creature card from your graveyard to your hand. If mana from a nonland source was spent to cast Ivier, return that card to the battlefield instead.

[+1]: Augur. (Look at the top card of your library. You may sacrifice a creature to put it into your hand. Otherwise, put it back or put it into your graveyard.)
[–X]: Exile target card in your graveyard with mana value X. Copy it. You may cast the copy without paying its mana cost.
[–6]: You get an emblem with “Whenever a creature you control dies, search your library for a creature card, reveal it, and put it into your hand, then shuffle.”

Whenever Witchfinder Artur enters or attacks, each opponent mills two cards and loses 2 life.
Whenever you cast an instant or sorcery spell, you may exile target instant or sorcery card with mana value less than that spell's mana value from an opponent's graveyard. If you do, cast a copy of the exiled card without paying its mana cost.

Haste
Battle cry (Whenever this creature attacks, each other attacking creature gets +1/+0 until end of turn.)
Whenever Goblin War Chariot becomes crewed, untap each creature that crewed it with mana value 1 or less. This ability triggers only once each turn.
Crew 3

Inquirer, Roaming Rover attacks each combat if able.
Whenever Inquirer deals damage to an opponent, draw a card.
