Jiro, Artisan of the Deep

Activated abilities of food tokens cost {1} less to activate.
{1}{b}: Exile a Fish, Jellyfish, Kraken, Leviathan,
Octopus, Serpent, Oyster, Squid, or Whale from
your hand or from play with a menu counter on
it and create a food token.
If an opponent casts a spell with the same converted
mana cost as a spell exiled with a menu counter on
it, that player loses life equal to the converted
mana cost of that card.
