Great 1 off to deal with wide strategies in 5C Humans that runs Karakas.
@ChubbyRain You are running 5C Humans man (which was never about running exclusively humans). Very small differences and nuances from the lists I am trying out. I love the path you have taken and the card choices are overall strong. You can always go sensei top and a planeswalker or two in these kind of approaches. But I must warn you, once you play Top in 5C Humans (which is also not about running 5 colors per see) you will include it in all the lists where you can shuffle your deck.
I personally am not a huge fan of Tireless Tracker. Maybe this can be Dovin.
So this is a 'value' humans list that I designed and am trying out these days
Here is the link if you prefer written version or if the picture is not HD enough for you:
5C Saheeli Humans
I was running Felidar instead of Huntmaster and it might still be a good idea. But Huntmaster feels good as well. When you add 1 Felidar you want more Saheeli and then you want more Felidar. So I just want to keep the focus as much as possible. Grind them out and make value. Counter key tier 1 strategies in the process.
I am pretty sure Lavinia is good in any deck that can support her in the current meta.
However, to exploit her ability to the fullest, recurring wasteland strategies are in my opinion the best way to go.
A card like Stifle also comes to mind as an additional way to lower the land count of your opponent.
@revengeanceful
It is not that hard, the less lands the opponent has the stronger Lavinia is.
Are you actually asking to explain you the reasoning behind the addition of Lavinia or are you just criticizing or shocked that people are putting Lavinia where she belongs, in a aggro control deck?
I already explained the reason with 1 sentence, and the key words are land destruction or Prison (works well with Lavinia). I do not think running Lavinia in SB of some blue random nonsense deck is the way to go to make her shine.
After testing various iterations with Lavinia my thoughts are that the card shines best in Prison Humans.
@rat3de
This can work actually. But it is a variant of Survival.dec I don't know if this is really on topic anymore 
Yes, it is an attempt to play revokers and Knot's with the colorless mana. Basically the idea is to play Revoker on ravager or ballista but also able to shut off noble/drs/planeswalkers. Just more threats you know. You are spending the 2 mana anyway, and with Thalia in the deck as well, revoker can be cast easier. I still kept some null rod and added chalice. Chalice for 1 is really strong in combination with Lavinia in this deck.
@Stormanimagus
By the way, I just got a 4-1 with Bant Prison Humans. I streamed it. I was 4-0 until the last match and last game. Opponent had a crazy unbeatable hand in game 3 so nothing I could do there. Deck is really not bad at all.
