There are a number of mechanics that make Skyweaver a game that’s easy to jump into, but at the same time provide a lot of depth for advanced players. Some examples:
Glory:
Activates the effect described when the Unit attacks and damages the enemy Hero (not other Units, though!)
Death:
Triggers when the Unit is destroyed and sent to the graveyard. Note that Dusted Units will not trigger their Death effects.
Play:
A Play effect happens immediately when the Unit is ‘played’ from hand.
Inspire (X):
Activates when you summon a Unit or Spell that matches the secondary condition, within parentheses. For instance, a “Inspire (Metal): 1 Damage to a random enemy Unit” would cause 1 damage to a random enemy unit whenever you summon any Metal Unit or Spell.
Sunrise:
Sunrise effects trigger at the start of your turn.
Sunset:
Sunset effects trigger at the end of your turn.
