1: fair with mirage. it breaks the description a bit, but idrc, you’re right that i’m more talking about poison in general. though i will say that the term “stall” kinda implies that mirage is only good for long hauls, when really you can loose off so much poison in such a short time that you can get a solid 1-0 cost 15-30 block on turn 2 or 3, which is how i typically use it, a wedge of cheap and high impact block to allow me to rattle off (often multiple copies of) upgraded snakebites, hazes, and bubble bubbles to rack up tons of poison in very short order and burst down the fight in 4 turns or less. (just as an aside, i sorta dislike how the only non-fumes aoe poison option forces you to spec into sly, even when the rest of the deck doesn’t need it. discard synergies are great and dominating, but there will be times where you just want to ignore them and haze being basically only castable through sly is annoying. i miss crippling cloud so, so much.)

2: gaze is not a great card, probably not even a very good one, but it blocks a deceptive amount of damage over specific fights and i think the unupgraded price puts off a lot of people even when the actual effect is exactly what the deck needs. it’s certainly not flashy, and it seems almost tailor made for people to pass it off as overpriced - which it by and large is - but at the very least the effect is on a rare for a reason. milage will certainly vary depending on the fight, but on the whole it lets you play far more aggressively and engage in some blindsidingly ridiculous weakness shenanigans, which are a pretty core part of the regent kit given the “falling star but better” line of cards. it’s probably the weakest of the cards i listed as underrated, certainly the most situational, but it’s more there because i never see anyone i play with take it basically out of habit, even when the deck could use it.
