Laboratory of Magic

This enchantment enters the battlefield with one experiment counter.
At the end of your turn, if you did not cast any creature or Planeswalker spells during your turn,
you may search your library for a non-creature,
non-Planeswalker card with a total converted
mana cost equal to or less than the number of experiment counters on this enchantment and
put that card into your hand then add an
experiment counter on this enchantment.
