Magic: The Gatherings Booster Fun scheme has felt a lot less fun recently
All of them have spiked massively with the release of Avatar: The Last Airbender in late November
There are also a few from Final Fantasy (and maybe Assassins Creed) that could work in the right build
Cantrips, some of which could draw you lots of cards (like Foreshadow + Portent), could draw you into the lands you needed, but sometimes you just used one of your Counterspells to stop whatever they were doing for the turn and give yourself another turn to try to draw land
Search your library for a card that shares a color with a legendary creature you control, reveal it, put it into your hand, then shuffle
Since you have a few different mana rocks that generate mana and can untap themselves like Basalt Monolith, you can generate infinite colorless mana
