This Sheoldred is one of those generally good cards, but it can work especially well in decks that fill your own deck with cards, giving you lots of creatures to choose from for reanimation
They will not overwrite effects that modify power or toughness without setting it (whether from a static ability, counters, or a resolved spell or ability), nor will they overwrite effects that set power and toughness which come into existence after they resolve
