How does Last Rites work?

To understand how Last Rites works, it is important to distinguish between its Equip ability (which gets it onto the board) and its Effect (which allows you to play units from your trash).

1. Equipping Last Rites

• Cost: To play the [Equip] ability, you must pay [C] (1 Power) and Recycle 2 cards from your trash.
• Restriction: According to RiftJudge FAQ #8719, you must be able to pay the full cost to initiate the ability. This means you must have at least two cards in your trash to recycle. If you do not have two cards, you cannot equip Last Rites.

2. The Triggered Effect

Once equipped to a unit, Last Rites grants that unit the following ability: "When I conquer or hold, you may play a unit from your trash. (You still pay its costs.)"

• Trigger: The ability triggers whenever the unit equipped with Last Rites participates in a "Conquer" or "Hold" event on a battlefield.
• Presence Requirement: Per RiftJudge FAQ #9486, the unit equipped with Last Rites must be present on the battlefield at the exact moment the conquer/hold event occurs for the ability to trigger.
• Timing: When this ability triggers and resolves, you may play a unit from your trash. Because the card text does not specify a restricted window, this allows you to play the unit bypassing normal timing restrictions, even during your opponent's turn.

3. Sequence of Play

According to RiftJudge FAQ #9486 and FAQ #1014:

1. Trigger: You conquer or hold a battlefield. The ability is placed on the chain.
2. Resolution: When the trigger resolves, you decide whether to play a unit from your trash.
3. Playing the Unit: If you choose to play a unit, it is placed on the chain as a pending item.
4. Finalization: You must be able to pay the full cost of the unit you are playing. Once you finalize the unit (choose its location and pay the cost), it immediately resolves and enters play.

Note: This is my interpretation based on the card text and retrieved FAQs. No official core rulebook section explicitly details the "play from trash" window, so I have relied on established RiftJudge FAQs regarding this specific card.
