Return to Innocence

(You may cast a legendary instant only if you control
a legendary creature or planeswalker.)
Unless you have more than one opponent, cast
this only at the beginning of your upkeep
You have two target players exchange life totals.
Your life total becomes 20.
Each player shuffles their hand and graveyard
into their library, then draws seven cards.
Exile Return to Innocence.
"In the end Dakkon went back before the beginning."
