Ki Barrage

At the beginning of the end step if a creature you
control dealt damage to a player this turn add {r}. This mana can only be spent on instant &
sorcery spells & is not lost as steps & phases end.
Profanity- If you have 6 or more legendary cards
in your graveyard, a single Addendum spell can
be applied to end phase instead of main phase.
If this is destroyed all mana produced by it must
be spent by your next upkeep or its lost.
