Po (and All That He Entails)

Po cannot be blocked by creatures that are taller
than him (use your best judgement).
Whenever Po attacks, his controller and the
defending player take turns exiling cards from
the top of their library, placing them on a pile.
When a card shares a type with the card beneath
it, the first player that says 'snap!' may play one
or both of the matching cards without paying
their mana costs.
