Cosmo: Changed “a deck” to “a player deck or the encounter deck”. Removed reminder text

Should read: “Interrupt: When Cosmo attacks or thwarts, name a card type, then discard the top card of a player deck or the encounter deck. If that card is of the named type, Cosmo does not take consequential damage for this use.” (Changed “a deck” to “a player deck or the encounter deck”. Removed reminder text.)
