Wrath of Retribution (Red)

A Draconic attack becomes a chain link when it resolves as a layer on the stack and becomes attacking. This means going from the layer step of combat to the attack step of combat.

If the combat chain is open, you are still considered to control a (Draconic) chain link, even if the attack is no longer on the combat chain. Last Known Information is used to determine the type of a chain link.

Decreases to resource costs are applied after increases to resource costs. If an effect would increase the resource cost of playing Wrath of Retribution, the decreases would be applied last.

Wrath of Retribution triggers when it resolves on the stack and becomes an attacking card. When the triggered effect resolves, any daggers you control will get +1 and cost less to activate for the remainder of the current combat chain. This will also apply to any new daggers that come under your control after this triggered effect resolves.

If you play a Kiss of Death after Wrath of Retribution’s triggered effect resolves on the same combat chain (e.g. played via Infiltrate), Wrath of Retribution’s +1 continuous effect would apply to Kiss of Death; however, the cost decrease continuous effect will not apply as it would only apply to daggers you activate, not daggers you play.
