Thank you! Regarding Chronoshift, you're right, the marked champion inevitably ends up alive and with the exact amount of health they had upon being marked, regardless of how much health they gained or lost in-between. Aside from thematic reasons (i.e. Zilean reversing his opponent's state in time), I think it could be appropriate because Chronoshift's current heal-on-death leads to this awkward situation where trying to kill a marked target ends up giving them even more of an advantage, and so attacking them doesn't feel good and ends up turning the whole thing into a pseudo- with an even longer duration. With a perfect reversal, killing your opponent would disable them, even if they wouldn't be "dead" for good, and there would be no situation where damaging your opponent would leave you worse off than if you didn't, barring cooldowns.
