Card Rulings talk:U.A. Blockbacker

Why provide information on a card that's cited no where from the TCG-side. Think about how advanced the game is. Citing information without evidence defeats the whole point of references. Cases like U.A. Blockbacker's Trigger Effect vs. Damage Step in terms of activation legality should be left to the interpretation of the Head Judge. If you dislike this route, then you simply apply the OCG Ruling unless there is a major citation within OCG Damage Step rules OR the card database that explictly states cards of this nature cannot activate during the Damage Step.

Also, if there is a TCG Source, it has to be Judge Forum viewable or PDF viewable currently otherwise it's just talk without concrete fact.
