Originally, I had the blue ability as "Draw a card. ~ doesn't untap during your next untap step." But that seemed too good.

So this is a "Better than an ETB tapped dual", apart from being vulnerable to a wrath?

Seems strong. Card draw would be sickeningly strong. (Oh no, I missed a land drop; in exchange I get a card every other turn)

V: It has the major restriction that you can't play it turn 1, unless you have an Ornithopter.

The effects are minor enough that you might be able to get away with this. I'd be interested to see if you can come up with a full cycle's worth of effects for the different colours. I guess "Target creature gets +0/+1" is probably small enough.

It also is weak to combat. It isn't a good land if you're behind.

@Alex: The issue with targetting is that it means it's no longer a mana ability:

Mm, good point. Finding five untargeted abilities that are weak enough and colour-affiliated could be quite tricky.

It should be the next Multiverse Design Challenge.

I've been pondering it, and it's very hard to find nontargeted, simple, weak effects for a cycle.

Brainstorming possible effects:
­: Add to your mana pool. Put the top card of your library on the bottom of your library.
­: Add to your mana pool. Put a random card from your graveyard on the bottom of your library.
(These wouldn't go on the same card.)
