Additionally, you are very likely (but not guaranteed) to get more Avatars within the booster packs themselves
It doesn't fit into a Control shell either, as the first chapter of Summon: Esper Maduin cares about permanent cards, not instants or sorceries
Green-black mostly falls on the less-aggressive side, though, since its big advantage comes from attrition through removal
Even if the deck failed to outright kill in one turn, that failure didn't use up all your resources, so you can try again later
In all honesty, fat packs and bundles are my favorite ways to enjoy the paper version of a new set because it strikes the perfect balance of product variety, number of booster packs, and price point
The Final Fantasy Source Material version is on the higher end, too, coming in at $86 a copy
