Jace's Erasure no longer has the "always yes" option.
When placing an ability trigger from Jace's Erasure on the stack, you can right-click the trigger to open a menu of options.
Among these options are: "Always yield", "Yield until end of turn", and "save targets".
There should be a fourth and fifth option: "Always yes" and "Always no".
This would vastly speed up playing with this card on MTGO.
