"Draw a damage card, check icon. No 'X' so I'll be drawing another, has a '+' so I get one more total. Draw another, now I have a '-' so I get one less total. Wait, how many do I have left to draw again?"
pretty much what I instantly thought as well
ts to much bookeeping
its already a struggle to reference your min/max damage draws and make sure you aren't cheating
So I would just take those epic shots (that are fun, for that guy) and make those the rare limited choices. For glass cannon cards that allow the player to get that high, they need to have more downside.
So obviously, fragile is a downside, but we could push that. High damage cards come with like x2 or x3 fragile icons, or we just add x3 in that bubble- so now you have to really consider your situation. If you wanna pop 50% of an enemy tank, you as well get 50% easier when they shoot you.
Additionally, while more complex, we would add another space for an icon under the damage draw- so when you flip this uber damage draw card, something else negative triggers. Adversely, when you flip a weak boring damage draw card, thats weak- it does some other perk like heal or refresh a card, ect and you just fullfill everything as you flip
