Could you please clarify, what the "Hero" tag does in Ceo?
If I understand it correct dot is a slower lightning, which is (Unblockable), but has (Ranged) pretendRps tag, since it's from a gun.
How does the (Trigger) work? Is it once per turn? Which priority does it use? Can it only target empty locations? If not, does it kill stuff? Is there a phase when it happens, or can it happen always? Is it (Unblockable)?
How does Space out work? Is it (Unblockable)? Is it a destroy? Other details?
