$150 isnt out of the question, especially if Slivers are confirmed at some point, but the ship has probably already sailed on making any reasonable profits here
Although, if Godzilla cards were printed today, that'd probably be the case
However, if a player intending to utilize this deck loads up on cheap counter-spells, they should fare pretty well
Zen Takahashi While I believe that Prismatic Ending is a better card than Solitude, as shown by how much more the former sees play in Legacy, I do believe that in the context of Modern, Solitude is the best white card in the format
One thing strongly in the favour of Forbid in the cube as opposed to any other format is that there being only one copy of any given card there is quite a sharp tail off in the quality of groups of spells
