A lot of interesting decks there; I'm sorry to see the Baneslayer Angels in that last one, it's nice when decks are affordable.
Anyway, two comments: Regarding the first deck, a Teetering Peaks-Ball Lightning combo is 8/1, not 9/1. Second, regarding the second deck... I like the idea, but Khalni-Heart Expedition seems out of place here. Also, if you're going to run Trapmaker's Snare in a 3-color deck, shouldn't you have more than one sort of Trap available, at least in the sideboard? It seems like one Mindbreak Trap main could definitely pay off against Cascade, and an Arrow Volley Trap in the side might help against some types of beatdown.
He realized just now that Burst Lighting is strictly better than Shock!
Anyway, there's nothing wrong with a 9/1 Ball Lightning bouncing into the red (and we mean red) zone off a Teetering Peaks.
