that makes sense for mind hunter- just for clarification, is the target's ability usable for more than one turn, only one turn, or more than one turn until another target is selected?
for dementia- does "uses a skill" include passives, or just activated? ie if a graveyard has it, and a skeleton is produced after a creature dies, does that create an event in which dementia can be triggered? or is it just when say an hourglass is clicked? if it includes the passives, a slight alteration of wording may be used along the lines of "Target creature or non-pillar permanent has a 30% chance to delay itself for 3 turns whenever it attacks, has its skill activated or triggered"
