Opt lets you balance your deck, like other cheap cycle cards, while also increasing consistency like scry lands do, yet affords you more flexibility and options as to how and when you use it than basically any of the alternatives
Cultivate Search your library for up to two basic land cards, reveal those cards, put one onto the battlefield tapped and the other into your hand, then shuffle
Chaos Warp In all honesty, Chaos Warp should be a bit lower in this list if we look only at cold, hard efficiency but Magic is a game, after all (even if we forget about that fact sometimes!), and as one of the best Polymorph effects in MTG Chaos Warp can be hilarious
Even if you only draw 1-2 cards after wiping the board, this can be backbreaking in mid-range mirrors
I also think itll be fun to make Peacock an indestructible God with Tyrite Sanctum
