Thats because each box includes 24 Jumpstart boosters, and every pack contains 20 cards, including all the lands you need to play
The Land Flip Gods Im dealing with these all together because for each one, outside of Commander, Im not sure the front side is quite good enough for the rate
There's also Helm of the Host for a more permanent alternative, Sword of Feast and Famine to untap all your lands twice for peak combat trickery, and Sword of Wealth and Power for lots of spell copying and Treasure tokens
Colorless creatures is what you key on here
Similarly, if an effect creates a token and puts counters on it, the additional tokens will also get those counters
While it can be intimidating, having a solid plan from the beginning can make the project easier
