Its a pretty obvious combo that is fast and surprisingly powerful
Its backbreaking when you go Exploration plus a land, and the next turn you drop two lands
Now, you don't necessarily need all of them, but several of them could fill slots in your deck, and be 2-for-1 deals
The less you have to pay for these types of effects, the better that way, you can start to repopulate the board immediately on the same turn, putting you in position to be the first one that untaps with creatures, and the first to attack again
