Overall, I'm quite pleased with the list
While Phasing can be strong in certain strategies, this ability is a huge downside for creatures as they are not able to attack the turn after they come into play, so theyre pretty slow
Now you've got a flier that can do the trick, or Radiant Fountain or Obscura Storefront or a crazy turn 1 foreshadow of Leechridden Swamp #37
Across it, like a river, streamed a line of creatures
You can use it on your opponent's turn to tap a creature and tap another one on your turn to shut off two blockers your opponent has before your attacks, something especially good in limited formats
It is less onerous that the universal hard counters like Force of Will, Cryptic and actual which all need much heavier blue commitments
