When cast, Conduit of Ruin allows you to search your library for any colorless creature card with a converted mana cost of seven or greater and put it on the top of your library

For a simple solution, the BCW 300 Count Card Box has more than enough room for a cube of 360 cards

The two ways around this are to either be so fast and so dominant that you overwhelm the table before anyone can mount a response an inconsistent strategy at best or you fill your deck with enough protection and recursion that you can survive long enough to exploit an opening

If Comeuppance has zero fans, I am dead

Those Commander decks will probably also be running Armageddon, which is functionally identical to Ravages of War, right down to casting cost and MTG color identity
