Taunt it's an ability for protecting its hero. All cards with taunt your enemy has, need to be destroyed or silenced before you can damage any card with no taunt or the enemy's hero.
The rest means that at the end of a turn, that card will add +1 damage point and +1 health to all the rest of the cards in your team.
The joke is the large text thing.
I read your answer and I read the card pieces of information again and I think I also/even understand a thing.
Now, I am also curious about why people write something about themselves but strikes it down... Is it like about something that does not relate to themselves? And how they, however, can find something to write about themselves that does not relate to themselves?
