Core Reaction (Yellow)

Core Reaction triggers at the beginning of your action phase. This triggered effect is a targeted effect: you must declare any target when you add this triggered effect to the stack. When the triggered effect resolves, you will destroy Core Reaction and deal the prescribed amount of damage to that targeted object.

When resolving Core Reaction’s triggered effect, there is no priority between any of the effects generated (e.g. destroying, dealing arcane damage)

If an effect that increases the arcane damage of the next card you play applies to Core Reaction, that effect will not carry over across turns to when it triggers on the next turn.
