Hi.
Imagine a Heroe is attacking a jet trooper, he defends with 3 blocks and the heroe attacks with 3 damage but he's got with him "tactical display". Would it be possible to convert 1 block to 1 evade and remove that posibility if the heroe wanted to use tactical display?
Maybe in the step 4 (apply modifiers) the heroe has to use first the tactical display card and then the jet trooper can choose whether convert it or not.
