i dont know why, but I love this

interesting but some problems

azorius doesnèt usually care about lands, so getting lands into your hand is odd. maybe just "At the beginning of your upkeep, reveal the top card of your library. You may put that card on the bottom of your library, otherwise put it into your hand"

also the last line needs a capital letter on Cast

you are right, but the problem for me is wording, you don't CAST lands, they aren't spells, and i cant say put into play, because that wont work for instants and sorceries. so either of those don't work, meaning i changed the card to only do nonlands, since that's a better ability anyways, you don't want to play lands as much as awesome spells. Also, I will fix the typo immediately. Thanks :)

very nice. I like this idea.

Kind of terrifying the amount of stuff this will let you drop into play. Some of it you'll know what it is; some you won't. But you won't care, 3 mana for "Cast something good" is a supremely wonderful thing.

Very mythic.

Hm. Yes. Cast this and crazy big stuff happens shortly thereafter, semi-unpredictably. Yep, sounds like a good mythic.

I'm still not 100% sure whether this breaks colour pie or not. I guess Omniscience and Mind's Desire let you cast arbitrary cards in monoblue, so yeah, it's probably fine.

I would say, this looks nice in azorius and is likely legal, but it probably fits better into mono-blue

then again it is an enchantment, which is pretty white stuff, so i guess azorius is a good mix of two colors.

also it just feels azorius, especially cause that is the colors you normally get aether in

also both white and blue use strategy to shut down oppponent strategies, and this does that by nullifying effects that put cards on the bottom of the players deck, so this would fit into both for this reason too

thanks for the nice words :D
