Blue Library Manipulation

So the typical card draw/filtering for blue needs to deal with the fact that the blue-red and the blue-black identities are different. There needs to be consideration of both scrying for red and the possibilities of playing things from outside of your hand for black.

So let's start with this set's version of Telling Time:

Putting a card on the bottom of the library rewards the blue-red scry-to-the-bottom gameplay. Putting a card in the graveyard makes it accessible for possible recursion or playing out of the graveyard later, or even a reave kicker with a black or red card.

Here's the draw three sorcery:

I had an idea of having blue and black spells that have inherent bonuses if they're played from outside your hand. I don't want push into that too much because it's so very parasitic and not terribly compatible with reave in black. But I might have one or two cards. Scour for Answers does go great with the set's mandatory Weird Blue Enchantment:

I think this is okay as rare and not mythic. To explain what's gong on with the scry components: In a limited environment with less emphasis on sorceries and instants, players might be concerned about exiling a bunch of cards they can't play. The scry on ETB before the exile is intended to let the player improve their chances of getting playable cards. They can bottom lands or creatures. And then the activatable scry is simply to make sure it's never a "dead" enchantment if you don't get any castable cards or after the cards have been cast. And it also makes the card compatible with red-blue.
