Biolume Egg // Biolume Serpent rulings

  • You can't sacrifice Biolume Egg unless another effect allows you to.

  • You may sacrifice any two lands with the subtype Island to activate Biolume Serpent's ability, even if they aren't basic or aren't named Island.

  • If a permanent that isn't a double-faced card becomes a copy of Biolume Egg and then is sacrificed, that card can't be returned to the battlefield transformed. It will remain in the graveyard.

Biolume Egg // Biolume Serpent keyword rules

Transform Rule 701.28

To transform a permanent, turn it over so that its other face is up. Only transforming tokens and permanents represented by transforming double-faced cards can transform. (See rule , “Double-Faced Cards.”)

Although transforming a permanent uses the same physical action as turning a permanent face up or face down, they are different game actions. Abilities that trigger when a permanent is turned face down won’t trigger when that permanent transforms, and so on.

If a spell or ability instructs a player to transform a permanent that isn’t represented by a transforming token or a transforming double-faced card, nothing happens.

If a spell or ability instructs a player to transform a permanent, and the face that permanent would transform into is represented by an instant or sorcery card face, or is a transforming token that was created with an instant or sorcery face, nothing happens.

Some triggered abilities trigger when an object “transforms into” an object with a specified characteristic. Such an ability triggers if the object either transforms or converts (see rule ) and has the specified characteristic immediately after it does so.

If an activated or triggered ability of a permanent that isn’t a delayed triggered ability of that permanent tries to transform it, the permanent does so only if it hasn’t transformed or converted since the ability was put onto the stack. If a delayed triggered ability of a permanent tries to transform that permanent, the permanent does so only if it hasn’t transformed or converted since that delayed triggered ability was created. In both cases, if the permanent has already transformed or converted, an instruction to do either is ignored.

Some spells and abilities refer to a “transformed permanent.” This phrase refers to a permanent on the battlefield with its back face up that’s also a transforming double-faced card or a transforming token. A permanent with its front face up is never considered a transformed permanent, even if it had its back face up previously.

Defender Rule 702.3

Defender is a static ability.

A creature with defender can’t attack.

Multiple instances of defender on the same creature are redundant.

Scry Rule 701.18

To “scry N” means to look at the top N cards of your library, then put any number of them on the bottom of your library in any order and the rest on top of your library in any order.

If a player is instructed to scry 0, no scry event occurs. Abilities that trigger whenever a player scries won’t trigger.

If multiple players scry at once, each of those players looks at the top cards of their library at the same time. Those players decide in APNAP order (see rule ) where to put those cards, then those cards move at the same time.

An ability that triggers whenever a player scries triggers after the process described in rule is complete, even if some or all of those actions were impossible.
