The top 64 was also exceptionally diverse. The top 8 of Atlanta was hugely diverse with 2 RUG Delver, 2 Turbo Depths, 1 Burn, 1 Storm, 1 Dredge, and 1 UW Control ("Miracles" but not packing any Miracle cards). 4 out of 64 is more of a showing than Dredge has had in a while, but it's a far cry from broken or what Hogaak was doing in Modern where it was the most played deck and Leyline of the Void was the most-played card and it was still making up half of all top 8's. I don't think it's a hugely problematic card though. And it's made some appearances in BG Dark Depths lists as well, though none of those showed up in the top 64. It showed up in the top 8 of GP Atlanta in a Dredge list, and there was two more in the top 16 and another in the top 64. They'll passively pick up loyalty by using these abilities, keeping them in play for a lot longer.It's definitely a competitive card. This is especially great for Planeswalkers with zero-cost abilities, like Tyvar Kjell Garruk, Cursed Huntman and Ugin, The Spirit Dragon. Every ability is effectively 'cheaper', with negative abilities taking less of a chunk out of your 'walkers, and positive ones having more of a boost to your loyalty.

The second benefit does apply more specifically to Planeswalkers, but having loyalty abilities cost +1 loyalty extra is something a lot of unaware players might trip over, thanks to it being framed more like a negative. Being able to get chaff off the top of your library is always a good move, and for four mana Carth does it excellently.

You don't need to hit a Planeswalker card with it, and if you do you can just opt to put it on the bottom of your library along with the rest. However, Carth has two incredible abilities that make him a real powerhouse. A black/green Planeswalker-heavy deck might sound a bit limited, especially when you consider how many of Golgari's strategies care more about creatures.
