Bringing Endra combo back in Echoes of Eternity.
The only new cards in this deck are Pause for Reflection and Nahid's Distillation. Pause for Reflection is perhaps the best spell in the game for protecting Endra since it can bounce her at fast speed, while Distillation is solid card draw in the mid-late game.
Endra: fairly standard
Skycragg Banner: extra power/influence
Bore: attachment removal, especially for Avigraft (who ruins this deck kind of hard)
Edict of Shavka: fairly useful anti-aegis tech
Garden: this is also useful as attachment removal, but it also doubles as card draw and/or an answer to Tocas, who kind of hits this deck pretty hard.
Edit: Distillation replaced with Trailblaze. If you think of the draw tools as "combo gatherers" and "combo extenders", Trailblaze is good at both while Distillation is good at extending the combo but not to gather the combo due to its high cost. It also has this cool feature where if you want to protect your Endras but also want something to do if you don't need to protect them (for example, using her mastery trigger), you can use Trailblaze since it's a fast spell. Took Flame Blast out of the market since it generally wasn't needed since you have burn in Torch and Display of Instinct, and found that Edict of Shavka was a useful alternative.
