Plaid Hat Games is having an official iOS Summoner Wars tournament. If you enjoy SW and have the iOS version, there's no reason not to join. You can sign up at this link here or discuss it here.
They want 108 players and there are only 10 spots left. Winner will get $100 in gift cards to spend at Plaid Hat Games. A fun twist this time around is everyone has to play more variety in their factions.
BTW, if you upgraded to iOS 7, then you may have issues with the app.
