If you're going to main deck the Eidolon I would take out at least 2 Hushwing. I just hate the idea of one or even two dead cards sitting around in a midrangey plan like this one.

I would also consider going down to 3 Coursers. They are super strong but having multiples in hand doesn't seem very good to me. I'm not sure how often he gets removed in your meta though so keep that in mind.

I would put in Banishing Light for whatever spare slots you end up with. Card is just op.

Aracknid, I agree with your dead card thing- it's my main reservation. However, Constellation is still triggered off of enchantments, so Siege and Enchantment removal, as well as Bestow, can still trigger it. But for now it will stay sideboarded, coming out mainly against control when I need the draws. As for courser I don't see a problem with running the full 4 but I will consider it with the Banishing Light.Hushwing Gryff is great as it deals with most of the threats in standard right now, but I do need more ways to deal with Pear Lake Ancient, as it can't be countered and I can't rely on Siege to stick around till turn 10+.

I agree with Hushwing being Sideboard... 2/1 flying for 3 is poor quality, especially since you may often not need the Flash ability (because of Prophet). When you don't need it's ability it's a bad card.

I would consider Thassa, God of the Sea as a replacement... though you wouldn't expect to make it active. - for a draw-go type of deck, the Scry every turn is great, and then making creatures unblock able just puts the finishing touch on Sagu Mauler... I could be wrong, she may not be that good.

This is a cool deck, have you done well with it?

Whisperwood Elemental instead of Ethereal Ambush maybe?

Dissolve may be better than Dissipate...

Dissipate exiles queen and co. for against whip decks, and I'm not gonna pay 40 bucks for elemental (plus it doesn't have flash :P ). I'll consider a playset if the price drops though.

What? No Banishing Light? <Very good removal, as it can target gods/indestructible things.

Also, Very rogue. Very rogue indeed.

Yeah Banishing is very good, it's in my side right now though. I think I like the 75 I have (mostly) just trying to figure out which is main and which is side

I suddenly realized I should probably have a way to buy back cards from my graveyard. Unfortunately, tasigur doesn't fit in my colors.
