Ok thanks, I didn't know he would have to replace the sphinx, also I like the idea of broodmaster in this since I own 2 of it already and I haven't used them. I am still trying to find a card to replace 1 Kiora, the Crashing Wave, but I am having trouble because I don't want to swap something new in if I only run 1 of it. I'm thinking of in my own version of this maybe swap one Kiora, the Crashing Wave out and 1 Hypnotic Siren out and add in 2 of a new card, I just wanna know what card I would and whether I should. Thanks.

Unless there is a specific reason for running 4 Kiora, the Crashing Wave also I found a different solution possibly just add 1 more Jace in place of her.

The reason I like 4 Kiora, the Crashing Wave is the increased consistency of drawing her. Also, unlike some other planeswalkers (even Jace), drawing multiples (even in the opening hand) isn't terrible. I've frequently dropped her Turn 3, -1'd into a fourth land, then Turn 4 dropped a fifth land, -1'd into a sixth, and had seven mana available to play a new Kiora, the Crashing Wave plus a Courser of Kruphix/Thassa, God of the Sea/Hour of Need, or even Hypnotic Siren on their Butcher of the Horde / Goblin Rabblemaster / Polukranos, World Eater.

A 3rd Jace, the Living Guildpact for consistency is tempting, but I don't feel that you get as much LASTING gain from his -3, just a tempo boost. And, you can't -3 a second time directly into another Jace the second turn, so drawing multiples isn't as easily mitigated as Kiora.

In the games I have played with the deck, I find that unless I am able to play Jace Turn 3 (to accelerate draw disparity and maximize likelihood of opponent discarding their hand), I often will want to play anything in my hand OTHER than Jace.

Perhaps Bow of Nylea for the death touch aggro? Synergies well with Kiora's Follower. Or maybe two Bident of Thassa going with the "Blue devotion matters theme" from my earlier post? If you do opt for the bidet though, definitely keep in all 4 Hypnotic Siren. ;-P

Ok I think I will stick with 4 Kiora thank you

I AM tempted by the Bident of Thassa idea... but I don't know what to sub out for it... Polukranos, World Eater is just too good... I prefer Jace, the Living Guildpact to Bident... I also just argued for 4x Kiora, the Crashing Wave... Where would Bident go?!
