Senior Enchantress Teacup

Whenever a creature enters the battlefield, that creature's controller creates a Food token. (It's
an artifact with "{2}, {t}, Sacrifice this artifact: You
gain 3 life.")
Creatures can't attack you or a planeswalker you control unless their controller pays {x} for each
of those creatures, where X is the number of
Food they control.
"But first, a cup of tea!"
