Speaking of Proliferate, Tidus isnt the only card in the set that can go wild with that mechanic
hard to get something that's stuck to a land without land destruction, and if left untapped, you can always just get the card back, potentially baiting it out

Or at least cheapens any big costed moves you might be planning to take
You might play less than four or put in ways to sacrifice your lands for a benefit
