Familiar Explained

•Familiar cards can't be cast from anywhere until
the Contract cost is paid.
•If you do, the card is exiled to the Summon Bar
where you can cast it from the Summon Bar
normally at any time.
•When a familiar leaves the battlefield you
may exile it into your Summon Bar. It costs {1} more to cast for every time it enters the
Summon Bar after the first time it was cast.
