Looks like the new FAQ reversed a few email rulings we'd gotten.
Phantoms can't use Advanced Sensors to cloak then immediately decloak. This might say some interesting things about when abilities are declared, and when their conditions are checked, and what it means for chained abilities... Or maybe not. As always, who knows?
Rexlar also gets to flip bonus cards from Minor Explosion, which I like. Not sure why they changed that, and I really wish they'd made it a more general rule... Does it apply to extra damage like Porkins hurting himself? Shrug.
