I was wondering if there were any other cards similar to dash hopes and browbeat? I was wanting to build a fun deck where an opponent has to make all the decisions. I would prefer more in red and black to put in some burn, and keep it in the color pie, but if I have to make it more fun and less competitive, I'm completely fine with that.
An ability exists on the stack independently of its source. Removal of the source after that time won't affect the ability. Some abilities cause a source to do something rather than the ability. Any activated or triggered ability that references information about the source checks that information when the ability is put onto the stack. Otherwise, it will check that information when it resolves. If the source is no longer in the zone it's expected to be in, its last known information is used.
Book Burning
Breaking Point
Lethal Vapors
Temporal Extortion
Flaming Gambit
Skullscorch
I think all of these besides book burning will be worthwhile additions. Thank you very much.
