Flash (You may cast this spell any time you could cast an instant.)
Flying; fear (This creature can't be blocked except by artifact creatures and/or black creatures.)
When Dust Elemental enters the battlefield, return three creatures you control to their owner's hand.

Enchant creature
You control enchanted creature.
At the beginning of your upkeep, enchanted creature deals 1 damage to its owner.

Choose target creature. Reveal cards from the top of your library until you reveal a nonland card. That creature gets +X/-X until end of turn, where X is that card's converted mana cost. Put all cards revealed this way on the bottom of your library in any order.

Whenever another creature enters the battlefield, you gain 1 life.

Choose one —
• Search your library for a basic land card, reveal it, put it into your hand, then shuffle your library.
• Return target creature card from your graveyard to your hand.
• Target creature gains flying until end of turn.

Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.)
Choose target card in a graveyard other than a basic land card. Search its owner's graveyard, hand, and library for all cards with the same name as that card and exile them. Then that player shuffles their library.

: Draw a card and reveal it. If it isn't a land card, discard it.

Until end of turn, target creature you control gains trample and gets +X/+0, where X is its power. Sacrifice it at the beginning of the next end step.

, , Discard a card: Target creature can't be blocked this turn except by artifact creatures and/or red creatures.

All Slivers have ": If this permanent is on the battlefield, flip a coin. If you win the flip, exile this permanent and return it to the battlefield under its owner's control at the beginning of the next end step. If you lose the flip, sacrifice it."

Artifacts, creatures, and lands your opponents control enter the battlefield tapped.

Fungal Behemoth's power and toughness are each equal to the number of +1/+1 counters on creatures you control.
Suspend X—. X can't be 0. (Rather than cast this card from your hand, you may pay and exile it with X time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)
Whenever a time counter is removed from Fungal Behemoth while it's exiled, you may put a +1/+1 counter on target creature.

Choose one —
• Destroy target artifact.
• Target creature gets +1/+1 and gains trample until end of turn.
• Remove two time counters from target permanent or suspended card.

Creatures you control get +1/+1.

, , Discard a card: Creatures you control get +1/+0 until end of turn.

Flying
Suspend 4— (Rather than cast this card from your hand, you may pay and exile it with four time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)

Return target creature you don't control to its owner's hand.

Flying
When Gossamer Phantasm becomes the target of a spell or ability, sacrifice it.

Trample, haste
At the beginning of the end step, sacrifice Groundbreaker.

Echo (At the beginning of your upkeep, if this came under your control since the beginning of your last upkeep, sacrifice it unless you pay its echo cost.)
When Hammerheim Deadeye enters the battlefield, destroy target creature with flying.
