/*
Six broad categories of devices to be identified through analysis:

1- Passive keywords (loaded/unloaded keywords, etc)
    a- Permanent
    b- Conditional on the below

2- Costs (bearer must be, etc.)
    - "Bearer must be"

3- 'When' effects (one-time)
    a- Cost
    b- Effect
    c- Optional/Required

4- 'Each Time' effects (recurring, "At the start")
    a- Cost
    b- Effect
    c- Optional/Required

5- 'While' effects (continuous)
    a- Cost
    b- Effect
    c- Optional/Required

6- Actions (at-will)
    a- Phase/Response
    b- Cost
    c- Effect

~ Costs precede the word "to" and are followed by Effects
~ All Events are optional, as are abilities
~ Discard from play, as opposed to other locations
