I was intrigued by rule 706.10 and wants to confirm I understand the rule correctly.

Boros Fury-Shield is cast using red mana. On the stack it is copied. Will the copy deal damage?

Latchkey Faerie is cast for its prowl cost. On the stack it is copied. Will the copied creature trigger to net a card?

Boseiju, Who Shelters All is used to cast a Lava Axe. On the stack the Axe is copied. Will the copy be uncounterable?



As I understand the wording of 706.10 the answers are yes, yes, no. Correct?

706.10 To copy a spell, activated ability, or triggered ability means to put a copy of it onto the stack; a copy of a spell isn’t cast and a copy of an activated ability isn’t activated. A copy of a spell or ability copies both the characteristics of the spell or ability and all decisions made for it, including modes, targets, the value of X, and additional or alternative costs. (See rule 601, “Casting Spells.”) Choices that are normally made on resolution are not copied. If an effect of the copy refers to objects used to pay its costs, it uses the objects used to pay the costs of the original spell or ability. A copy of a spell is owned by the player under whose control it was put on the stack. A copy of a spell or ability is controlled by the player under whose control it was put on the stack. A copy of a spell is itself a spell, even though it has no spell card associated with it. A copy of an ability is itself an ability.
