King of Tokyo: Powerup has an evolution card for Meka Dragon called Mecha Blast that reads:
Discard this Evolution to deal 2 extra damage.
There is also a discardable card from the main game called High Altitude Bombing which reads:
All monsters (including you) take 3 damage.
Can Mecha Blast be played after/during High Altitude Bombing to make it do 5 damage instead of 3 to everyone?
