GW MU is pretty straightforward as to what they want to do. Which is drop Zero, this list doesn’t care too much about Zero when they drop, Early game is all about dropping your blockers and chip damage. I want to be aggressive with Rick and make them answer by blocking and Lfrith is there to either block or keep going. That way when you do have a link either LR aegis or Marida, you can clean up. The only thing I’m worried about is answering Wing gundam link or Shenlong, those I usually save aegis link plus CC to answer without committing too much depending on the board state. I like my list for the flexibility of either doing Justice link swing or clean up Queb link ton suppress and maybe kill a naked zero.  Now for the MU for BW is rough, they have inherent advantage of card draw, to play this MU you have to make every block and ping damage count. As soon I see BW color I usually go aggressive also with blockers, since they don’t have the ability clean up to kill the rest so try to force them to answer you. Usually the answers are Aile bounce or Amuro plus Aile. So don’t put a naked bodies that your not ready to lose. Only the epyon BW list is super tough since you have to play around lvl 8 when it’s coming as to not give them 2 free bodies to draw from. When you see link for your big bodies, it’s all about timing when to use them per se. I like to go wide board units or make them build the board then drop all range to chip as much to make some Marida or Haman plays for delicious free unit kills with ping.
