Flow

Description
Certain spells and artifacts will generate stacks of Flow when used, and each spell you cast makes you lose one Flow stack. Some spells will gain bonus effects while you have Flow stacks.

Spells with upgrade count as two spell cast and consume two Flow stacks.

 * The artifacts and  negate this anti-synergy.
 * High or the upgrade  is needed for the constant casting of this spell.
 * Spells like and  do not have synergy on their own - a Flow deck needs spells that can actually be, like  and . These are also the spells you probably want to use your Upgrades on.
