Unreleased tip: On your first runs, start with a returning class (Ironclad/Silent) to transfer STS1 patterns, then deliberately sample both Act-1 Alternate Acts to learn which relics/cards spike in each environment
Survival is still decent in a selection of creature heavy midrange decks where you have utility creatures, late game finishers you don't want early and ramp dorks you don't want late
Creatures, sorceries, artifacts, other enchantments, everything's flash-able, allowing you to hold your resources open to cast whatever you like on other players' turns
Gengar VMAX is really just breathtaking
It can clean out anything like planeswalkers, enchantments, artifacts, and dorks with ease, just as long as they all have the same cost, and the XX will get you to the perfect number for blowing up
