I agree you need storm in there otherwise the devils simply fly in to wreck havok. And originally we were assuming storm was cast by your opponent. It's cast to stop the devils flying even at the cost of halving missle effectiveness.

But CPs other point is that you would normally have blockers. Who at that stage is going to use archers against you with no blockers? Especially if they are using Storm themselves to stop the devils flying!

Because your blockers may/should have decent shields then they are likely to take less damage from friendly fire archery than the unshielded devils even under darkness induced archer inaccuracy.

And if storm has been cast defensively then he can also cast Wind Guide to buff his archers.

I am not sure blockers would overcome the other points Baalz made - Storm Demons, Horrors etc. But I think it would be fair to assume they would be there and storm (Storm Demons aside) counteracts the flying to mean they have to be fought.
