Evolving WildsMy Walkers:Jace, Telepath Unbound: This card works fairly well within my deck. His +1 (after flipping) allows me to steal a creature via Willbreaker, while his -3 lets us cast any of our sorcery/instants from the graveyard. I don't always care for his creature ability, though, because I don't always want to discard any of the cards in my hand.
Nissa, Sage Animist: My second favorite out of all the Origins planeswalkers, after Liliana. Her creature form isn't bad. Her flipped +1, however, is basically "either draw an extra card or play an extra land this turn," and her ultimate has won me games in the past.
Nissa, Voice of Zendikar: I'm not sold on her in this deck. I like all of her abilities, but not as much as I'd like an
Altered Ego. I've been looking for a slot for the Ego, and it's either going to be this Nissa or the
Duskwatch Recruiter.
Kiora, Master of the Depths: She's great for this deck; her +1 can steal a creature or create a blocker, and give you that extra mana source to pull something off. Her -8 isn't too relevant, and her -2 works fairly well. If I cut the Recruiter, it would be better.
Jace, Unraveler of Secrets: I have no opinion on this card yet. I seriously just added this card, swapping out a [Pore Over the Pages[/card] after I drew him. He seems like he'll work better than the Pages, though.
My Best Creatures/Spells:Willbreaker: He steals the opponent's creatures with ease. One time, I was playing this deck in 2HG and I had control of every monster on the field (it's worth noting that my partner was running a control deck that didn't play any creatures while I had the Breaker).
Bounding Krasis: He's an all-star of the deck. His flash + tap/untap combo means that I can steal one of my opponent's creatures any time, even after they've declared attackers to get 2 extra blockers with Willbreaker, or allow myself to push through a blocker by flashing him out in the end step. I wish I could run 4.
Retreat to Coralhelm/
Retreat to Kazandu: The guy talking about this deck in the forums said he used U/G Willbreaker with the Retreats. These guys let you snag an opponent's creature just by playing a land (hence 4 Evolving Wilds) or gain life/scry. The biggest downside is that if you steal an opponent's monster with Kazandu, they get it back with a +1/+1 counter if they kill your Willbreaker. However, you can use these counters to boost the Willbreaker out of range of sweepers like
Languish and
Radiant Flames. These guys are also why I have
Herald of the Pantheon.
Outland Colossus: I just wanted a win condition besides for Willbreaker. This can, and has, won without either the Willbreaker or the Colossus, but he's always nice to play as a threat.
There's a chance that some of you will notice my lack of
Sylvan Advocate and
Tireless Tracker. Well, I don't have either of them. Even if I did, however, I think I would only play 1 Tracker, as I'm trying to stay away from cards that can't help trigger Willbreaker.
