Test your reflexes!
No rounds. No turns. Everything can happen simultaneously, except that if there's a timing conflict between opposing player's effects the player who begun to declare their effect first gets to decide the order.
Mage channeling = 1 mana / second
A creature has a charge time of 4 seconds before it can be activated for the first time in the game, and then 2 seconds before it can be activated again. Your mage's quickcast action can be used without charging it.
(1 second = about 2 human-perceived instants).
Hope you like!
