Saint Nicholas, Giver of Gifts

Hexproof, indestructible

creature tokens.
During each player's upkeep, that player creates
a 1/1 Christmas Spirit, then creates X treasure
tokens, where X is the number of Christmas
Spirits they control.
{r}{g}: Transform Saint Nicholas. Activate
only if no opponents control a Christmas Spirit
