Flying, prowess
Whenever Surveyor of Skies attacks, you may return a permanent you control to its owner's hand.

Put any number of target creature cards from your graveyard on top of your library.
You draw two cards, and you lose 2 life.

When this permanent transforms into Worthy Vulpine or at the beginning of combat on your turn, creatures you control gain haste and trample until end of turn.

Flying, haste
You may reveal each card you draw as you draw it. Whenever you reveal a creature card with mana value 1 or less this way, create a token that's a copy of it. That copy gains haste until end of turn.

{T}: Add {C}.
{1}, {T}: Add one mana of any color.

Reach
When Sage of Staves enters, choose one —
• Sage of Staves deals 3 damage to target player or planeswalker.
• Put a +1/+1 counter on target creature you control.

Choose target creature card in your graveyard that was put there from the battlefield this turn. Return that card to the battlefield tapped.
Fabled {3}{B}{B} (Then if you cast this for its fabled cost, put it onto the battlefield transformed attached to that creature.)

Tithe (As you cast this spell, you may tap three artifacts and/or creatures you control.)
Creatures you control gain indestructible until end of turn. If this spell's tithe was paid, put a +1/+1 counter on each creature you control.

Flying
When Krothuss, Abyssal Terror dies, return all creatures to their owners' hands except for Krakens, Leviathans, Octopuses, and Serpents.
Foreshadow {6}{U}{U} (You may cast this spell for its foreshadow cost. If you do, also trigger its “dies” abilities when it enters.)

Target player sacrifices a creature.
Fabled {2}{B} (Then if you cast this for its fabled cost, put it onto the battlefield transformed attached to that player.)

Rhapsody {4}{U}{U} (Pay {4}{U}{U} to cast this as a 4/4, or as a sorcery to make it become a 4/4.)
Whenever you cast a noncreature spell, Triumvirate Inductee gets +1/+1 until end of turn. Then if its power is 4 or greater, you may tap or untap target permanent.

Combined Generator can't be blocked except by three or more creatures.

Defender, trample
Tap any number of other untapped creatures you control with total toughness 8 or greater: Formidable Bulkvine's base power becomes 8 until end of turn and it can attack this turn as though it didn't have defender.

Improve {1}{W} ({1}{W}: Put a +1/+1 counter on this creature. This costs {1} more to activate for each +1/+1 counter on it. Improve only as a sorcery.)
Prevent all combat damage that would be dealt to attacking embattled creatures you control. (A creature is embattled if it has a counter on it or has a permanent you control attached to it.)

Flying
Effigy of Wisdom gets +1/+1 as long as your fealty to Islands is four or greater. (Each Island you control counts towards your fealty to Islands.)

Whenever Twitchy Pyromancer enters or attacks, it deals 1 damage to any target. Whenever a creature dealt damage this way dies this turn, upgrade Twitchy Pyromancer. (Give it one of the listed counters it doesn't already have.)
• +1/+1
• Menace
• Prowess

As Angelic Barracks enters, you may pay 3 life. If you don't, it enters tapped.
{T}: Add {U}, {R}, or {W}.

Scry 2, then draw two cards. You gain 2 life.
Monument {2}{W}{U} (You may cast this transformed from your graveyard for its monument cost. Exile it if it would leave the battlefield or not resolve.)

Choose three. You may choose the same mode more than once.
• You draw a card and you lose 1 life.
• Target opponent discards a card and loses 1 life.

Flying (This creature can't be blocked except by creatures with flying or reach.)
Vigilance (Attacking doesn't cause this creature to tap.)

Search your library for two basic land cards, reveal them, put them into your hand, then shuffle. (Then exile this card. You may cast the creature later from exile.)

Tzelin of the Demon Realm can't block.
Whenever a Demon you control enters, you may pay {B}. If you do, return Tzelin from your graveyard to the battlefield with a +1/+1 counter on it.

As an additional cost to cast this spell, discard a card.
Create three 1/1 red Soldier creature tokens with haste.

When this creature enters, it seeks secrets or valor. (Give it that Oath Aura. Fulfill secrets by attacking with it and two or more other creatures to draw a card. Fulfill valor by dealing combat damage to a player to create a 2/1 white Soldier token.)
Arise {3}{B}{B} ({3}{B}{B}, Exile this from your graveyard as a sorcery: Create a black token copy of it that's also a Zombie and can't block.)

As Forgotten Idol enters, choose a card name.
Spells with the chosen name can't be cast.
