I'm a big proponent of spells that counter others. WS may be too strong/too easy to cast, but adding say a battlefield version of dispel or changing the dynamic of battlefield enchants--maybe working them like globals so that only the most powerful one(s) can exist at a single time would be interesting. In such cases spells like Gaia's Blessing that place an effect on all friendly units could be changed from Battlefield enchants (spells that produce effects on a cyclical basis) to Mass enchants (spells that create a durable effect).
