Gilles, The sea- dog nerd

if Gilles, The sea- dog nerd deals damage to an opponent or planeswalker draw a card and search your library for an island and put it in play tapped.
if you control 5 or more islands and have at least 4 nerds on the battlefield transform it.
When Gilles was 10 he had a disease and started to cough and then transformed into a sea- dog. At school, he learned how to transform back into a human, but if there is to much water he immediately transforms back into a sea- dog.
