It also sounds quite nice versus Reanimator, Sneak and Show, and Marit Lage decks. I have tested it once against Miracles. It won the game, but didn't particularly shine in this matchup. I did find the double green hard to get, making me cast it a few turns later than I could have cast an Ugin.
During my hiatus, I would occasionally play UG Eureka/Show. I did a lot of testing with Sandwurm Convergence. I was testing it over Ugin because when everything happens at the same time, needles/revokers could come down and name Ugin. IThere are a couple things I recollect from my testing of SW Convergence.
-Against Grixis Delver they can not remove it, however... assuming they have DRS, they can still drain you out before you can wurm them. (This situation happened to me on mtgo.)
-Delver will have spell pierce/daze/FoW, so it's not trivial to get it into play.
-UB reanimator can still tidespout tyrant it to beat you. It's a solid lock against the rest of the deck.
-Sneak and Show can beat it if they have cunning wishes.
- I tended to board it in against any fair deck because the constant supply of 5/5s is hard for most decks to deal with.
