This has obvious yet significant implications for linear combo decks which need help accelerating to their game-winning turn, especially ones which already focus on lands, like Lotus Field decks in Pioneer
It's not enough for you to just make sure you have enough Humans on the battlefieldyou need to have enough in your deck for your Courageous Outriders to consistently hit
You can also play Field of the Dead and Scapeshift to mix up your strategies, assuming neither of those cards gets banned
Well of Lost Dreams excels in that aspect: A colorless card that probably fits black or white decks
Its also worth mentioning that this doesnt just happen during your turn, but each turn, so if you have anything that allows you to cast spells from exile on your opponents turns this would trigger then as well
