At the beginning of your upkeep, put a verse counter on “My Past is Not Today”.

, Sacrifice “My Past is Not Today”: Exile up to X target cards from graveyards, where X is the number of verse counters on “My Past is Not Today.” You gain 1 life for each card exiled this way.
Not sure if I can fit this in. Could be common or uncommon. It doesn't work with Phoenix Ascension as well as it looks. It could be an okay cheap/common Song for a deck with lots of Bands, but doesn't do much in most decks.
