I would honestly change up the 2
Needle Spires and 2 Shambling Vents in place of 2 Battlefield Forges and 2
Caves of Koilos. Sure you'd be taking 1 life per tap but your easily making that back with your Fiendslayer Paladins. Sure you won't be able to make creatures out of your lands but instead you'd be able to make a stronger early game without those lands coming into the battlefield tapped.
