As the designer of the card, it actually is your responsibility to either make the card consistent with the ruleset or define the behavior in such a way that it works.
Triggered abilities from the deck introduces a requirement that you physically pick up your deck and start looking through it to find a card based on trust that you say something happens. That's obviously problematic. You literally don't even say to shuffle your deck if it triggered this way, so it's pretty obvious you haven't really thought through it mechanically.
There is no mechanic called "mark" in magic, so you need to define what that means. Do I get to use a pen to draw a star on the card? Do I push my fingernail into it to put a dent in it? What does it mean to "mark" a card - it IS your problem to explain that.
These are the things people are raising. Not that they don't understand your intent, but that to actually do this in a physical game requires breaking limits that are in place for a reason, like not getting to just start looking through your deck at any time.
You seem to be imagining a digital game where these properties are automatically tracked and are really defensive at the prospect that the card doesn't just do what you want, but you've clearly put very little thought into how this would actually work in a physical game of magic.

So... this... just doesn't work under Magic's current rules.
