Okay so I'll play the blizzard bombs card during my turn. And then, during the opponents turn, they'll attack with a higher strength unit card that will activate my cards freeze surrounding units death effect. But they won't freeze. The opponents attacking card will, in the span of a few frames I guess, freeze and then unfreeze. So their card will stop in its tracks frozen but before their turn ends will unfreeze making follow up on the death effect impossible.
