Should the reflexive trigger system introduced in the Origins FAQ apply to any cards in Spiritforged ?

Yes! This is another one where if you don’t know the finer points of the rules, you’re probably already playing these cards correctly, but the machinery of the rules requires a slightly different wording than we thought. Reflexive triggers, identified by “do this:” language, create new chain items to handle things that need to offer players a chance to react, or just need to happen later than the rest of a spell or ability. This impacts 2 cards in Spiritforged , both of which let you play something and then try to do something to that thing. Arise! (revised text) Play a 2 [M] Sand Soldier unit token for each Equipment you control. Then do this: Ready up to two of them. Rell, Magnetic (revised text) Tank (I must be assigned combat damage first.) When I attack, you may play an Equipment with Energy cost no more than [2], ignoring its cost. If you do, then do this: Attach it to me.
