A proper Black Core card remains 100% opaque

you save 2 mana when casting Diluvian Primordial, 4 mana off Rise of the Dark Realms, and 8 mana off Emrakul, the Promised End

The limit to Johann's ability--that you can only do it once each turn, is important, because that means you can do it on yours AND your opponent's turns

Better yet, casting two or more non-creature spells (which you'll likely be doing already anyway) gives Lyse Hext double strike, meaning you'll be dealing double damage with any attacks on top of whatever effects come from the non-creature spells you've been casting (which, again, are cheaper thanks to Lyse Hext's signature ability)
