So I’ve given Slogurk a little more thought. As I said, it’s interesting because there’s not quite a clear way you’re intended to win the game with it. Which is cool in a Commander sometimes.

Simic value engine Landfall is probably the strongest way to build the deck, I’ll stand by that, but really if you’re not taking advantage of Slogurk’s abilities you would be better of just running Tatyova or Aesi instead.

Slogurk does two things, really: gets bigger when you do the thing, and can recur lands. For the first thing, it does have trample, so it probably is designed with intention to threaten your opponents’ life total at some point. Hardened Scales and similar cards will make it get bigger faster so it’s an effective threat. And there are a good number of cards that care about lands and +1/+1 counters, so that’s a good way to bridge the themes.

With the recursion ability, I think it’s usually better to just run ways to play the lands from your graveyard rather than putting them in the graveyard and taking them back out. But lands with a cycling or channel ability you might want to repeat would be good synergy. Though Boseiju is probably over budget.
