There are two major groups of static abilities:

Statics for the main 7 layers

Syntax:
S:Mode$ <Continuous> | <Affected$ {Valid Player/Card}> | <Layer-specific$ Params> | [Description$ {String}]

Here's an example for layer 7c:
Affected$ Creature.YouCtrl | AddPower$ 1 | AddToughness$ 1 | Description$ Creatures you control get +1/+1.

See StaticAbility.generateLayer() for the full list of params on each Layer.

Note: Layer 1 is currently only implemented as a resolving effect instead.

Statics for the concluding "game rules layer" (CR 613.11)

The available effects are defined here: StaticAbilityMode.

Note: some rules-modifying parts are still coded via Continuous mode for now, e.g. SetMaxHandSize$ {Integer}.
