Reveal the top four cards of your library. You may put a creature or land card from among them into your hand. Put the rest into your graveyard.

{2}{W}{B}: Exile up to two cards from a single graveyard. Recruit. Activate only as a sorcery. (Create a 0/0 white Soldier Army creature token, then put a +1/+1 counter on each Army you control.)

Reach
When Automated Overwatch enters, create a Function token with “If this spell would create one or more tokens, it creates twice that many of those tokens instead.” (It's an enchantment. As you cast an instant or sorcery spell, sacrifice any number of Functions to add their effects to that spell.)

Flying
Sacrifice a Fungus, Saproling, Plant, or Insect: You gain 2 life.

Whenever you cast a noncreature spell, scry 1.
{3}{U}, Exile an instant or sorcery card from your graveyard: Draw a card.

Whenever a creature you control enters, put a devotion counter on Monument of the Masses.
At the beginning of your upkeep, if Monument of the Masses has thirty-five or more devotion counters on it, you win the game.

Flying
When Bleak Condor enters, mill four cards.

Permanents you control gain indestructible until your next turn.
Fuse (You may cast one or both halves of this card from your hand.)

Create two 1/1 green Insect creature tokens, then put a +1/+1 counter on target creature you control for each Insect you control.

Sundappled Scrub enters tapped unless you control another Desert.
{T}: Add {G} or {W}.

Flying

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

Fire from Above deals 2 damage to target opponent and each creature with flying that player controls.

Creatures your opponents control get -1/-0.

Flying
Whenever Swiftwing Sphinx or another creature with flying deals combat damage to an opponent, put a +1/+1 counter on that creature.

Whenever you cast your second spell each turn, you may have Dormant Memory phase out until you cast your second spell in a turn. (While phased out, treat it and anything attached to it as though they don't exist.)
Fleeting {1}{U} (You may cast this spell for its fleeting cost. If you do, sacrifice it at the beginning of the next end step.)

Kernel Barrage deals damage to target creature or planeswalker equal to the number of spells you've cast this turn (including this one).
Flashback {2}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Ward {2} (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays {2}.)
Each creature you control with a counter on it has ward {2}. (If a creature has multiple instances of ward, each triggers separately.)

You may exert Accursed Bear as it attacks. When you do, it gets +1/+0 and gains trample until end of turn. (An exerted creature won't untap during your next untap step.)

Flying

Choose one —
• Target creature gets +3/+3 until end of turn.
• Target creature blocks this turn if able.
• Scry 1, then draw a card.

Counter target spell. Scry 1.

Clash at Geier Reach deals 2 damage to each opponent and to each creature and planeswalker they control.
Cycling {2} ({2}, Discard this card: Draw a card.)

Flying, vigilance
{2}{G}: Return target creature you control to its owner's hand. If you do, this creature gets +2/+2 and gains trample until end of turn.

{1}{G}, Remove a -1/-1 counter from a creature you control: Wiltthorn Elemental gets +2/+2 until end of turn.
