Non-Avatar creatures can't attack you or planeswalkers you control unless their controller pays {2} for each of those creatures.

{1}, Sacrifice Ruinous Proselyte: Destroy target artifact or nonbasic land.

Whenever you cast a spell, Scorned Figurant gets +1/+1 until end of turn.

Flash (You may cast this spell any time you could cast an instant.)
When Spell Shackle enters, exile target instant or sorcery spell. (That spell won't resolve.)
{1}{U}, Sacrifice Spell Shackle: Cast the exiled card without paying its mana cost.

Ravaged Monument enters tapped.
{T}: Add {G}.
{2/G}{2/G}: Ravaged Monument becomes a 4/4 green Elemental creature until end of turn. It's still a land.

As End of the Empire enters, choose a creature card name.
Whenever a creature you don't control with the chosen name dies, create a 4/4 colorless Demon Spirit creature token with menace.

Target creature gets +2/+1 and gains haste until end of turn.
Agonize (You may cast this card from your graveyard by putting a -1/-1 counter on a creature you control in addition to paying its other costs. Then exile this card.)

Flying
When Curator of Curios enters, draw a card for each glory counter you have.

Enchant creature
Enchanted creature gets +1/+1 and has flying and prowess.

Flying
When Hallowed Perspective enters, investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)
You may exert Hallowed Perspective as it attacks. When you do, until your next turn, you may cast spells as though they had flash. (An exerted creature won't untap during your next untap step.)

As Superset enters, choose two abilities from among flying, first strike, lifelink, prowess, and vigilance.
Each creature you control with exactly one of the chosen abilities has the other chosen ability.

Flying
Whenever Yawning Crane deals combat damage to an opponent, target tapped creature that player controls doesn't untap during its controller's next untap step.

Enchant creature
Enchanted creature gets +1/+1 and has flying.
When Skypath Pilgrimage enters, journey twice. (Exile the top two cards of your library face up. Whenever a creature you control deals combat damage to an opponent, put a journeyed card you own into your hand.)

This spell costs {1} less to cast if it targets an embattled creature. (A creature is embattled if it has a counter on it or a permanent you control attached to it.)
Put two +1/+1 counters on target creature you control and untap it. It gains hexproof and trample until end of turn.

{1}, {T}, Sacrifice Aureate Panorama: Search your library for a land card that could produce each color of mana, put it onto the battlefield, then shuffle.

Enchant creature
Enchanted creature has winnow. (Damage dealt to it also causes its controller to lose that much life.)

Nip at the Heel deals 1 damage to any target. Create a 1/1 red Hound creature token.

Whenever Implant Tinkerer or another artifact you control enters, choose one —
• Put a +1/+1 counter on that artifact.
• Implant Tinkerer deals 1 damage to any target and you gain 1 life.

At the beginning of each opponent's end step, that player loses 1 life for each creature they control unless they sacrifice a creature. Then they lose 1 life for each card in their hand unless they discard a card.

Flying
Whenever Rimebreath Tyrant attacks, you may discard a card. When you do, tap target creature. It doesn't untap during its controller's next untap step.

Flying
Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.)

Enchant land
When Unexplored Regions enters, draw a card.
Enchanted land is an artifact in addition to its other types and has “{T}: Add one mana of any color.”

Erratic (When this creature dies, reveal the top four cards of your library. Put a creature card that costs less than this revealed this way onto the battlefield and the rest on the bottom of your library in any order.)

Haste
{W}, {T}: Tap target creature.

When this creature enters, you gain 3 life.
