Siegmeyer of Catarina

Whenever Siegmeyer of Catarina deals combat
damage to a player, it explores. (Reveal the top
card of your library. Put that card into your hand if
it's a land. Otherwise, put a +1/+1 counter on this
creature, then put the card back or put it into your
graveyard.)
"Mmm...mmm... Mm! Oh-hoh! Forgive me. I was absorbed in thought. I am Siegmeyer of Catarina."
