It's really amazing how long a tournament moderator can last on these forums.
For the time being, I'll be your happy tournament organisor! That said, here's a quick summary of the tournament statuses:

Good news for the relatively new CMC players! The NPC Tournament, run by me, is currently accepting participants.
Some rules:
- All participants must have 100 or less wins on their CMC account.
- All participants must be in possesion of a Forum account.
- Games are best 2 out of 3, single elimination.
- Minimum deck size is 30 cards.
- Maximum per card is 5 cards.
These and other rules are explained in the thread.
EDIT: This tournament is now only accepting alternates, as it's already 16 participants in size.

Also, I'd like to focus your attention on the Prism 2 tournament that Feral Noodle is setting up at the moment. The thread speaks for itself, check it out of you're interested in participating in a teamed tournament.

And, as a small note to the participants in the Holiday Tournament>: Round one deadline is postponed to Friday, January 21st, because of the CMC downtime past weekend.
