Hi, please find how I have builded my list with leyline :


It is possible to play with leyline but you have to modify your list to include discard on yourself. Thanks to that, you can have Turn 1 Leyline + your dredge discarted, and moreover you can mulligan to find your leyline ! It is a big impact for your SB and impact also your MD, but you want to include to the 75 cards :

4 leyline of sanctity
4 leyline of void

4 lion eye’s diamond
4 unmask

4 serum powder (to increase the % to find leyline and force)

Total : 20 cards !
Place have to be done in the SB but also MD.....


My list:


4 Ichorid
4 Unmask
4 Force of Vigor
4 Hogaak, Arisen Necropolis
4 Golgari Thug
4 Golgari Grave-Troll
4 Cabal Therapy
4 Phantasmagorian
4 Bridge from Below
2 Shambling Shell
4 Narcomoeba
4 Nether Shadow
4 Stinkweed Imp
1 Flayer of the Hatebound
4 Street Wraith
2 Prized Amalgam
3 Dread Return


SB: 4 Leyline of Sanctity
SB: 4 Serum Powder
SB: 4 Leyline of the Void
SB: 3 Lion's Eye Diamond



Unmask and force of vigor are main deck because there is no more place in SB, and can be useful G1 contrary to leyline/led/serum.
This list is less powerful G1 because balustrade spy is not here ( to make place), but you have a really plan with leyline and you don’t concede against bojuka bog. You can hardly search your leyline or your force because you can mulligan, which is not common for Manaless :)
I hope you will like it !
