Skulk is a evasion ability that appears on creatures, and any creature with it can’t be blocked by creatures with greater power than the skulk creature. And this one is truly simple as that’s really it. The power restriction is determined as blockers are being declared, and multiple instances of it are redundant, and there’s really not too much more to say about how it works.
Skulk was an attempt at creating a new evergreen creature keyword for Blue and Black to share, but ended up being a little too restrictive to have enough variation for that. It works best on small creatures, and quickly declines in quality as the creatures scale up. It very occasionally still pops up here and there in supplemental sets, but that’s likely the extent of it’s future in the game.
