Cannot Counter Spells Cast with Conduit of Worlds 2nd Ability
Steps to reproduce: Opponent uses Conduit of Worlds 2nd ability to cast a spell while you have a relevant counterspell in hand. In my instance they cast Liliana of the Veil while I was holding a Negate.
Platform: PC
Actual Result: Opponent cast Liliana via Conduit and the spell did not even go on the stack. I had no opportunity to counter it, nor to respond with any of my other instants.
Expected Result: Conduit of Worlds specifically uses the wording "Cast", so unless that is a typo or otherwise misleading, the spell that was cast with the ability (Liliana in my case) should have gone on the stack and allowed for a response.
I've so far only experienced this issue once, but I have also only seen Conduit of Worlds' 2nd ability used this one time so far. I would assume this bug applies to other cards cast with Conduit, and not just Liliana and/or Planeswalkers, but I lost the game that turn as a direct result of the aforementioned bug and thus did not have a chance to investigate further.
