I know you would rather not play creatures in favor of more enchantments for the Sphere of Safety, but personally I would be willing to sacrifice that for a couple copies of Herald of the Pantheon because its "ramp" effect is more efficient than simply getting a single extra mana from a Trace of Abundance, for example. Does it just mess up the curve or is there another reason for not including the Herald?

CheapnFast thanks for the suggestion! There are a number of reasons Trace is better than Herald.

Most importantly, a creatureless deck gets automatic card advantage because your opponents' obligatory Fatal Pushes and Path to Exiles are useless. Adding a creature to your deck is essentially a mulligan since it's the only target for removal. Second, like you said, Trace adds to the enchantment count for Sphere. Third, since we're usually playing one expensive spell a turn, Herald is rarely better. There are a total of ~8 cheap spells that have generic mana; we would need to play two of those for Herald to beat Trace. Finally, don't forget Trace also adds crucial colored mana because we're 3 colors splashing blue!

Those are all good reasons! Thank you for clarifying. As an aggro player traditionally I have definitely grown to hate Fatal Push and I think it is a big reason why creatureless decks like yours and Lantern control exists in Modern these days. I just wanted to hear the justification, and I suppose you do only have room for one spell per turn, so the two effects from the Herald and the Trace are equal now, thanks.

By the way I really like this deck, forgot to mention that. I always thought curses were cool.

Upvoted because I love enchantments being used in this manner.

Thanks for the interest!

Miasmic Mummy, vorpalaxe this works very well against my black deck before sideboard. gg

hmm I've been trying to think of how I could jam my favorite old combo of Possibility Storm and Curse of Exhaustion in modern, this might work out.

Has Open the Vaults been considered?

Hey thanks for the suggestion. What would Open the Vaults do for this deck though? The only payoffs are Search for Azcanta  ^Flip and Kruphix's Insight.

If you want to play it, you could build a Search, Kruphix, Commune with the Gods, Starfield of Nyx deck, like Seth's Starfield Paradox. But don't play Paradox because it's terrible.

If you want to play the Possibility Storm + Curse of Exhaustion combo, you could try Knowledge Pool/Possibility Storm + Curse of Exhaustion/Teferi, Mage of Zhalfir, giving you 8 copies of each combo piece.

Again the key is to focus on doing one thing. The more combos you put into a deck, the less likely you'll draw any of them, so it's just better to play fewer.
