someone mentioned mistveil plains but they neglected to mention tithe so you can find mistveil via sunforger.
also, orim's chant + mistveil + sunforger = hard lock on one player.
dawn charm can also make you very hard to hurt, and doubles as a counter and creature protection.
depending on your colors, bant charm can be awesome, but you've got to be playing 5 color. Also, there are lots of good counters that have some red or white in them, but most are unavailable to straight rw.
Thanks for all the responses! I am currently in the process of using jor kadeen as a new general. Unfortunately... There are are lot of good cards in red and white and I am trying to make a final list.
I think most often I find Wild Ricochet, but recently I've found that if no one else is playing blue a surprise Lapse of Certainty is usually enough to disrupt someone's plans long enough for the rest of the table to find an answer.
