Please remove the ability to summon Astels. This feature creates an imbalance in Avalon and can easily be exploited with deck effects and tonics. It is probably much stable to disable deck effects and astels. Also, why is there a feature to craft Avalon items and treasure? The more items there are the more complicated it gets? Why not just buff the stats or add another equipment type or tier. Maybe a Mythic just above Legendary which can hold 6 runes.
