In most competitive formats, cleaner discard is usually better: `Thoughtseize` is much stronger if legal, `Inquisition of Kozilek` is better in low-curve formats, and `Duress` is often better from the sideboard against control/combo because they do not draw a replacement

This is going to be a fun one to pull off, and were looking forward to trying it
