Hey Mark. My magic group just saw Krenko's Buzzcrusher, and there are some concerns.
It doesn't say target, and that's fine and can be expected on some cards, but it also doesn't say "choose", and now there is concern that it functionally won't work as intended because it doesn't tell you to select the lands you are destroying.
I understand this is a subject outside your area of expertise, but it's driving us wild.

I went and asked play design. The lack of targeting was done on purpose to help the card deal with Lotus Field, a popular card in various formats.

Using Bramblecrush as a reference, shouldn’t Green get to destroy planeswalkers? What about having creatures “fight” them?

The “destroy target non-creature permanent” effect predates planeswalkers, as we’ve been using it less specifically because of planeswalkers. Fighting planeswalkers feels more green, but it could have issues.

Crushing Disappointment is one of my favorite cards from the new set (Strixhaven). I love the flavor/lore but I also really like the mechanical game play of Black drawing cards and everyone losing life rather than just the player casting the spell. Can we expect to see more of this at high rarities or cards designed for constructed?

It’s something black can do more of.

The flavor texts of multiple cards, some of which were cited in the comments of the original ask, clearly indicate that Eldrazi stragglers do exist. Vestige of Emrakul and the UMA printing of Ulamog's Crusher provide decently indisputable evidence of this. As someone who very much disliked the way Eldrazi were handled in BFZ-OGW and SOI-EMN, I am glad to hear the focus is away from them, but excluding them entirely seems like a clear mistake. They are part of the world's identity now.

In spite of what characters of the world might think, Eldrazi spawns are extensions of the titans. If they are dead (or locked away in a moon), there can’t be any. I believe both flavor text comes at a time where people falsely thought they were dead.

What's the most general "destroy target" effect that's on-color for Green? I know "Beast Within" is a break, but is "Bramblecrush" on-color? Or is Green supposed to use creatures to kill Planeswalkers?

Green can destroy artifact creatures and flying creatures.

What is the mechanical weakness of Green? Green can destroy all card types (e.g. Beast Within and Bramblecrush + Rabid Bite) Green can generate mass card advantage (Collected Company, Praetor's Counsel) can tutor for lands & creatures or look and take cards from top of the deck like Black or Blue. It has efficient creatures of all sizes with trample, hexproof, deathtouch, flash, indestructible, vigilance, haste, tapping for mana, lure effect, curiosity effect, reach, infect and sometimes flying.

Green is over-reliant on its creatures. For instance, its creature removal and card drawing is tied to its creatures.

Is surge going to be an additional cost or a alternate the cost? The rules text and reminder text on Crush of Tentacles seem to imply different things

Alternate cost.

My problem with the Eldrazi is that a lot of them don't feel like anything special. Annihilator, while it had its problems, made them feel terrifying. Put an Eldrazi Devastator next to a Plated Crusher and tell me what makes them so unique and terrifying.

Annihilator had great flavor and horrible gameplay. Magic will fail longterm if we make it super flavorful but unfun.

What's the best thing of Blogatog?

Isn't planeswalker destruction in both black and green? After all, Bramblecrush was as recent as M14.

Green gets “destroy target non creature permanent” but it it never gets planeswalker destruction spelled out.
