Nagisa, Essence of The World

If this card would be put into the graveyard or
exile from anywhere, put it onto the battlefield
instead if no other Nagisa is on the battlefield.
Whenever a player adds mana to their mana
pool, negate that effect and all players add one
mana of any color to their mana pool instead.
{t}: All players get a Nagisa Emblem with
"{u/r}{u/b}{g/u}: draw a card for each emblem
you control."
