If you haven't played it before, either with the preconstructed decks Wizards makes for it, or with some mismatched Commander decks, I highly suggest it
What red card draw do you use
(Duress also has the advantage of being much better against Burn than Thoughtseize.) Spell Pierce is generally better than Unified Will, but it gets worse the longer the game goes on, whereas its pretty easy to turn on Unified Will in the late game with a Nexus or whatever lying around
This is conceptually a bit more complicate its a forgery in the sense that 2 real cards are glued together
One-sided cheap board clears are tricky to find, but options like Crippling Fear can make for a reasonable budget replacement
The reason is that I have included Blood Moon in my Top Five, a card which has not been picked by other others
