I think Gust will just make life kind of interesting. I'm going to get in the boat of people saying it won't come out until August to offset certain decks abusing it. I remember during the Base Set era Gust could also be used to buy set up time by bringing up something with an unwanted retreat cost and letting it sit for a bit. Assuming the rotation and the filler set no reprinting Warp Point or Warp Energy you're left with Switch, Fighting Tag and attacks/powers that switch you from the active position. Not sure if Switch will just become a normal play(more common?) or people will have to avoid high retreat cost guys to avoid being stuck with a random staller or what not.
