of course you team attack. Natasha is god. Wasp is run for the extra leaders, because she is god, so you don't miss your 2 drop, and because she is one of those cards you can feel good about under droping with.
Even initiative is alot better when you played quicksilver turn three and you have the option of droping wasp and natasha (and having rick jones just makes it even better).
Last I heard, stunning your opponent's whole board while you remain unscathed... was a good thing.
The prefered drop on each turn varies GREATLY depending on the matchup, the board, and most importantly, who has the initiative.
i'll go through avengers reservist and squadrion thogh since they are currently the most popular.
Obviously turn 1 is rick jones, if you miss him, it's not a big deal, you can play him later for a discard-or not, depends.
turn 2 we are already getting complex. I gtg, i'll finish this l8er
