I tried to make it as complex as i could so i've more draw engines: endra pappi+gardos(using chitta it's a very good removal for the early game) and get ready(for middle-late game). Also the strong guard is a very useful spell used in combination with impact of heavely violence and stronghold of lightning and flame.
Rose castle could ruin the early game for this. And then the mid and late game could be ruined as well because Rose is mostly seen in hand/zone controls. I'd recommend some Saint Castle as a countermeasure. Some Valkyrie Lupia might help too. Or Peace Lupia if rush is becoming a problem. Lastly I'd recommend more Stardust and less Asylum.
Other than that, pretty nice build. Endra is really awesome with Gardos and T4 angel drops like Leonidas. Get Ready is a cool backup too.
