Riffle shuffle/mash shuffle: Riffle/mash shuffling is usually thought of as the best way to shuffle, and guess what- it is
Its a simple but elegant loop
As far as self mill goes, I really like Cemetery Tampering
Just count it as a special bonus that Staff of the Ages stops all landwalk abilities, which also include cards like Livonya Silone and Ayumi, the Last Visitor
Its second ability, which allows it to untap by placing a -1/-1 counter on itself, is the key to its unique power
Second Winds recycle is also indirectly stronger after Uprising because, with the addition of Erratic Research and Grave Demon (plus a seemingly faster game pace), it is much less likely to win by drawing through your deck
