In
the end, it's a Foretell variant.
The key difference is that instead of paying [2] now to get a discount later, you pay the plot cost upfront and then you can cast it for free at sorcery speed.
Overall, it seems interesting. My only disappointment is that they are continuing this annoying trend of making mechanics that are similar to older ones instead of just recycling them. (I need to make a thread about that...)
