cycle of lands. Can also be "each opponent controls more lands..." but not sure if that's too weak.

Since it'll so frequently come up, cards like this should probably have reminder text: "(not counting this one)".

Doesn't this almost always entered untapped if you're on the draw? Which seems too little of a hoop to me

Yeah, it was meant to counter mana screw and to reduce the disadvantage of goind on the draw. Conversely, it almost always enters tapped if you're on the play right?

It has no effect on mana screw though. If you don't draw lands, who cares if they're tapped or not?

Sorry, I meant 'recovery from mana screw'.

Meaning if you miss one land drop, this will probably enter untapped, rather than a normal tapland that will still enter tapped on the turns that you need it not to.

This does actually seem like it'll be more often "I'm not first player? Great! I get free dual-lands!"

Which is maybe OK?
