When do aging card abilities take effect: when drawn, or at the end of the fight?
The publisher quoted the rule that the aging life cost is paid at the end of the fight, and the other aging effects follow the same timing.
Most take effect at the end of the fight, so you can still destroy or exchange the card first: the -1 life, -2 life and highest-card-equals-0 effects. Stop is the exception and applies as soon as it is on the left side. If you have zero life, a +1 life ability can still be used first, because it can be used at any moment.
