Player 1 has a single Fury Unit at a battlefield. Player 2 moves 2 of their units, a Chaos Unit and a Body Unit, to that battlefield. The Fury unit has an ability that reads "When I defend, draw 1". The Chaos unit has an ability that reads "When I move, draw 1" and the Body Unit has an ability that reads "When I attack, draw 1". In what sequence will these abilities resolve? AChaos, Fury, Body BChaos or Body, then Fury CFury, Body, Chaos DFury, then Body or Chaos EChaos, Body, Fury

The correct sequence for resolving these triggers is: Chaos unit's "When I move" trigger resolves first, followed by the Fury unit's "When I defend" trigger, and finally the Body unit's "When I attack" trigger.

When the Chaos and Body units move to the battlefield where the Fury unit is present, they initiate a move action. According to Riftbound rules (FAQ #6540, #3721, and #5806), "When I move" triggers must resolve entirely before combat/showdown initiates. Consequently, the "When I move" trigger from the Chaos unit resolves first.

Once those triggers are finished, the move is complete, which stages a combat showdown. Combat/showdown effects are then triggered. Following Rule 464.2.e.1, the attacking player (Player 2) places their "When I attack" trigger on the chain, followed by the defending player (Player 1) placing their "When I defend" trigger. Because the chain resolves LIFO (Last-In, First-Out), the defender's trigger (Fury) resolves before the attacker's trigger (Body).

Therefore, the correct sequence is: Chaos unit's "When I move" trigger resolves, followed by the Fury unit's "When I defend" trigger, and finally the Body unit's "When I attack" trigger.

Correct Option: E (Chaos, Fury, Body)
