I really like this design since its an effect that lasts throughout each players turn, and you get to change your target from turn to turn if you need to
(2021-07-23) Due to a recent rules change to cascade, not only do you stop exiling cards if you exile a nonland card with lesser mana value than the spell with cascade, but the resulting spell you cast must also have lesser mana value
The best way to exploit Chulane are cards like Shrieking Drake and Nurturing Pixie that bounce themselves or other creatures so you can constantly cycle through all of your mana
Klauths Will Definitely a card designed for Commander, Klauth's Will can be devastatingly destructive
That having been said, some sort of W/b/x(?) Tokens almost certainly will be viable
This isnt a land cycle that should be a staple or anything like that, but they should be played more than they are
