I always Port or Wasteland, so that didn't occur to me. I'm afraid the combo player will have 2 open mana on their turn. Very nice though, maybe I'll try that next time. My apologies to GoboLord.
Yes, that would be "big," considering the general concensus is if you have 6, you are playing too many. I would say diversity. TES is quite susceptible to mana denial. I'd get annoyed at Chalice @ 0, but I honestly don't think it alone will win the game.
Against Merfolk, mana denial + a clock usually kills me because I'm finding lands + Duress to get rid of countermagic + I'm getting beat. I think Mindbreak Trap in combination with Chalice + port and wasteland would have the same effect. I think discard is quite good against Combo, but only if they don't expect it. If you fetched Badland first turn, I think most combo players will see it coming.
agreed
