Merlin's Research

Look at the top 3 cards of your library. You may
choose an Instant or Sorcery card from among
them, reveal it and put it into your hand, than
put the rest on the bottom of your Library in any
order.
"These "planeswalkers" are remarkable. Able
to travel to other realms in the blink of an eye.
Imagine the wealth of secrets to learn in these remote
lands." - Merlin
