I use Oath of Jayce to get rid of Eldrazi I draw or that appear to be in my starting hand.
I then place them back with
Mortuary Mire on top of my deck so that I can choose from my graveyard (if I even have an option at that moment). After that I would tap my
Aetherworks marvel for a secured eldrazi/metalworks draw. So far I have almost never played that combo.
As of to running forests I have done this in the past. Yes woodweavers does cost a
forest which I never fail to create with
Aether hub so far. So that is +2 energy and not +3 you might say. Well thats true but with my deck im trying to keep artifacts on the battlefield as long as I can due to
Metalwork Colossus. If I do sacrefice it while atherworks marvel is up i still get 3 energy for it due to a permanent going to graveyard. Which could 4 if I ran
forest.
I used to play contigency plan (2mana blue card) instead of Oath of Jayce. Which often didnt help that much. And im thinking of running catheric reunion with the downside that you have to discard cards before you draw three new ones.
I have tought about running
vessel of nascency but I dont like the fact that the other cards go to the graveyard.
I dont think there is an
impulse in standard right now. Anticepate is the only thing that comes to mind that might be close to that direction.
I use mountains because I want to run Kozileks return, but im not sure how and what I will replace (and maybe for catheric reunion). Thank you for the suggestions!
