RoL gives AI something to target if it you keep it out. Also, you can't play SoP ahead if the others are missing against AI without PC control if you use a creature with defense. It' why I ran with ball lightnings in my deck. It's also not the speed of the combo but the speed of the splits, too, if you can get the combo off twice, your area fills twice as fast.
This is a faster but sloppier deck, it's also lacking the draw power but is more focused. It probably has a lower overall win rate, but a high efficiency rate against certain FGs filling the slot a traditional farmer works with where you do a bunch of skips. None the less, a welcomed member of the family.
