Happy Mask Salesman

You may have Happy Mask Salesman enter the battlefield as a copy of a creature or planeswalker
you control, except it enters with an additional
+1/+1 counter on it if it's a creature, it enters with
an additional loyalty counter on it if it's a planeswalker, and it isn't legendary.
"The mask that was stolen from me... It is called
Majora's Mask." -Happy Mask Salesman
