What if burier blink-tapped itself instead of mom-ing itself? Tbh i like mom-style protection though.
There's more problems than that mate.
Firstly, I'm not sure I like the P/T being set of specifically delved away creatures: The best ways to get delve working is with cheap instants/sorceries: Creatures you tend to want to stick around.
Alternatively, you can take the satyr wayfinder approach, but unless this is the only self mill reward card in your deck, you want to specifically keep those creatures in your yard for the bonehoard and co.
Assuming you want to keep the variably size, go for something simpler, like counting creatures in exile. The wombo combo with scavenging ooze is hardly worth the complexity.
Second, vigilance combined with the Mother of Runes clause (even only on itself) is pretty brutal. In addition to being exceptionally hard to remove (See bootman's comment) it also swings freely while shutting down the ground heartily, in addition to not being green/blue at all. Just scrap it.
If you want this creature to be resilient, let it regenerate, or gain hexproof or something. I wouldn't count mother of runes among the successes of the now abandoned protection mechanic, despite her power level.
If all you want is a "good" green delve card, we can make that. Hell, a colorshifted Gurmag Angler would work pretty well (despite your rage).
Is there a specific curve slot you're trying to fill? Delve (in practice) plays that whatever the spell is costs "about half" when played on curve in a fetchlandy enviornment, though the earlier turns tend to matter less and the later turns tend to matter more, lending Murderous Cut a more 3cc feel on average, whereas treasure cruise can cost 1-3 depending on when you need your draw spell.
Creatures are meant to be played as early as possible, as opposed to some delve spells, so the CMC will probably end up rounding up more often than down.
Maybe something like this?
