Ashling mechanic
A couple of weeks ago I saw this guy playing an Ashling the Limitless deck against a pod of 5 people. I think it was mid/late game, but basically at some point he killed the rest of the pod in a turn. I'm pretty sure he was using the discover mechanic, exiling cards from the deck and summoning creatures to deal damage, and to make it short he dealt a total of around 160 damage without even attacking. I have looked for a lot of cards, especially enchantments and cards with discover to see if I could replicate the strategy, but nothing I found seems useful for what I want to do. Any ideas about what cards he might have uses, or cards that could get me a similar effect? It seemed like he was discovering or cascading and dealing damage to ALL opponents with every creature summoned but I am not too sure.
