Heres the list so far: Major gains (30% or more): Minor gains (10-30%): Chalice of the Void, Noble Hierarch, Through the Breach, Doubling Season, Horizon Canopy, Engineered Explosives, Ancestral Vision, Mox Opal, Crucible of Worlds, Dark Confidant, Scapeshift, Brushland, Fulminator Mage, Ancient Stirrings, Lotus Bloom
Afterall, that's what this game is all about.

The list is focused on the Advanced Format, but the only difference between that and the Traditional Format is that all Forbidden cards in Traditional are simply just Limited: Forbidden Yu-Gi-Oh
Or Talrand, Sky Summoner
But - perhaps most importantly itll be the sort of mobile game that I boot and play in time that isnt wasted waiting for something or another
