Keyword notes

Transform - Put the X under this/it/him/her

Create a Y and put the X under it.

Transform is a discrete effect.
To transform subject objects into a specified object, first create the specified object in the arena if it does not yet exist, then put the subjects under it.
To transform objects into a token that does not exist yet, first create the token, then put the objects underneath it.
To transform objects into an existing permanent, just put the objects underneath it.
When used in conjunction with cards that flip (e.g. Invocations), the card is first flipped and becomes a permanent in the arena, then the transform will refer to that permanent as the specified object to transform into (the permanent to put cards under).
The transform fails if there are no transform subjects, or if they can not be put under the specified object for whatever reason.

Battleworn - Equipment that wear down after each time they are used to defend. If you defend with a card with Battleworn, put a -1{d} counter on it when the combat chain closes.

When you defend with a card it remains on the combat chain until the chain closes, therefore you cannot defend with an equipment multiple times on the same combat chain.
A -1 counter stays on the card until the card is destroyed or the game ends.
If the defense of a card that is defending is below zero, its defense value is considered to be zero.
When this card is destroyed, it is sent to your graveyard. (Not when it has 0)
When this card is destroyed, it is sent to your graveyard.
If the defense of a card that is defending is below zero, calculate as if its defense is zero.
