This rules it out for most styles of the deck
Those play from the top of your library cards, cards from exile, cards from the graveyard, abilities of cards on board, even cycling and ward costs are all fair game to spend this free five mana per turn on
Oriq Loremage (Chainer, Nightmare Adept) Having a repeatable tutor is a very powerful thing, and thats what Oriq Loremage offers us in Chainer
That's a little better than most mono-Green options like Trained Armodon or Nessian Courser
You even copy Voidmage Husher and Draining Whelk to counter spells and abilities at will
I usually try and select around eight cards for lists like this, but as with the previous colors, I may err on the side of shorter descriptions while cramming in more cards if the selection warrants it
