So I made a really cool Mono-Black Eldrazi Tron deck. The only decks it has lost to are Bogles and an Izzet Control that was running a few copies of Crumble to Dust. The only thing I can come up with for Crumble to Dust is Memoricide and/or Cranial Extraction. Does anyone know another or better way? And what could I do about Bogles?
What's good about the hand disruption is that it's just good in general, against most decks, and might even be in you main deck. The creature sacrificing is a bit more situational, but for decks that ramp w/o mana dorks, or bogles it'd be good to have in the sideboard.
It costs four mana. Just kill them before they cast it. Or, in black (and colorless, with Though-Knot Seer), use targeted discard to take it out of their hand, and then kill them before they draw another. You want some sort of targeted discard to deal with sweepers and such anyways, so this doesn't even have to cost a slot.
Land destruction spells don't actually do anything to protect against threats you have already resolved. It's disrupting spells that you might play later. So the solution is to punish them for spending an entire turn's worth of mana to kill your land, by hitting them with the threats you already have out.
