Build a 10-spellpoint academy deck. Your mage's life stat is lowered by 10. You can join the game at any time, you don't have to wait for it to finish.
When your mage dies you can respawn immediately. When you respawn, all your cards are returned to your spellbook, all your condition markers are removed, all damage is removed from your mage, and your mana is set back to your starting mana plus channeling.
You can leave the game whenever you feel like stopping, and you can jump back in whenever!
Have fun!
Note: It is your responsibility to keep track of your own channeling, mana and upkeep effects, as well as to know what your own cards do and anything else regarding spells and objects under your control. You also must do your own setup rounds before you post. No one is going to wait around while you prepare to enter the fray.
Also be courteous to other players and give them a chance to take a turn sometimes too. Don't monopolize the action phase.
Also if you want to keep track of your daily win/loss rate simply subtract the number of times your mage died from the number of times you killed a mage.
