Also consolidating it with Pedros's sideboarding, with minor discussion on hero's downfall inclusion after it.

Credit to Pedros for majority of sideboard and really a lot of things involving the deck. MDU as well. And the rest of ya' too, cause why not?

I didn't end up updating the sideboards for hero's downfall as much as I wanted, cause wasn't sure what to do with it in a lot of places.
I fit it into u/w and black devo comfortably, but I kinda wanted it in against esper midrange and control, b/w control, and mono-u, but wasn't sure what to pull to make room.
nAgainst b/w I feel cutting a land would be doable, since we're dropping dragons and main source of scry, so flood is more dangerous.
For esper control the only thing I can think of is a magma jet, but I do love me some scry and burn.
Esper midrange could probably just drop another Jester easily enough.
Mono-u is a bit odder, and I am not really sure what to pull out. Might only bring in 2 mortars and the downfall instead of the 3 mortars.
So those are my proposed changes. Thoughts?
