So the workaround, which seems pretty huge in fairness, has been to create a mechanically identical set to Marvels Spider-Man , only using the planes of Magics multiverse, instead of Marvels heroes, villains and the Marvel universes places and names
You can only use each of the following effects of "Floowandereeze & Robina" once per turn, and cannot Special Summon during the turn you activate either effect
The Archetype is 3/2, so Sun Quan is bigger, and then those things can be blocked by reachers, but there are no common keywords that will block horsemanship, so this is clearly the better class of card
The upside is interesting here, and in many EDH games, you should be able to mill 25+ cards with Space-Time Anomaly alone
