But what really kicks it over the top is that middle part of his text box: Whenever an opponent casts a spell, if no mana was spent to cast it, counter that spell. You dont have to worry about an opponent casting a Force of Will while tapped out, or a free Fierce Guardianship or Deadly Rollick

The latter two are cantrips and the first is a modal spell land you can toss in without pulling a nonland so all three have value

And that's one per food, not once per turn

This means that once you summon one and use its effect, you can immediately summon any other one and use its effect
