// Some continuous effects affect game rules rather than objects. For example, effects may modify
|
||
// a players maximum hand size, or say that a creature must attack this turn if able. These effects
|
||
// are applied after all other continuous effects have been applied. Continuous effects that affect
|
||
// the costs of spells or abilities are applied according to the order specified in rule 601.2e.
|
||
// All other such effects are applied in timestamp order. See also the rules for timestamp order
|
||
// and dependency (rules 613.6 and 613.7).
|
||
|
||
// Some of this rule modifying effects are implemented as normal CONTINUOUS effects using the Layer.RulesEffects.
|
||
// But if the rule change can be implemented simply by preventing an event from happening, CONTINUOUS_RULE_MODIFICATION effects can be used.
|
||
// They work technical like a replacement effect that replaces the event completely.
|
||
// But player isn't asked to choose order of effects if multiple are applied to the same event.
