Lorehunter

As long as you control a legendary permanent, Lorehunter gets +0/+2 and can't be blocked as
long as defending player controls a tapped land.
Whenever Lorehunter deals combat damage
to a player, investigate for each legendary
noncreature, nonplaneswalker permanent type
among cards in your graveyard. (Artifact,
creature, enchantment, land, and planeswalker are permanent types.)
