Well it doesn't help that that offense is rubbish
If you want to fare better against Teal/Tomb (or just Teal), cut a little bit of the gimick (in T1 you won't be able to paralyze enough quickly enough for it to make much of a difference) and shore up your defense with Demons. If you want to keep PG, use Magicians instead of Assyrians (Assyrians aren't good). Frog Demons is basically poo, since a Negatable immunity to Purple is like a lock with the combination written on the back.
Of course, some of the problem is that your offense is poo. This defense is actually pretty good (stalled me for a long time), but if your offense is inept, it won't last forever and will eventually crumble.
