Lightning, Lone Commando (Isshin, Two Heavens as One) Rating: 2/10 Isshin, Two Heavens as One naturally lives and dies by what kinds of attack triggers you have access to, because a 3-color vanilla creature is clearly unplayable
It also has the already mentioned advantage of being in pretty great colors for knight support
thats the side that goes through my printer first (its more or less symmetrical, but better safe than sorry)
The only real mistake you can make is not starting at all
If you have anther Pious Evangel with a Wayward Disciple , you can sacrifice some other creature to flip the Poious Evangel , and trigger the life gain/loss for the Wayward Disciple
Both plays might be kind of meh, but the fact remains you have a card that does something useful and something early late, and most cards dont have that kind of flexibility
