Artur Kogg, Educated Servant

When Artur Kogg enters the battlefield, if you
cast it, look at the top 3 cards of your library.
You can put an artifact, an enchantment, or a
legendary permanent card from among them
to your hand. Put the rest on the bottom of your
library in random order.
Whenever a nontoken artifact or enchantment
enters the battlefield under your control, you
gain life equal to the amount of nontoken
artifacts and enchantments you control.
