Forbidden lotus

When Forbidden lotus enters the battlefield,
Create X lotus petal tokens.
{t}: Add X mana in any combination of colors;
X is the number of lotus petals you control.
At the beginning of each upkeep,
if it is tapped, create a lotus petal token.
At the beginning of each end step, if it is
untapped, you gain life equal to the
number of lotus petals you control.
