This is a bit unfair since she just literally came out today, but consider Isatis in place of Chiro or Gatline. They're both really good, granted, but you ARE running a mono and that's just perfect for little miss support. She has high base damage, doing 6 and then the magic number 8 with clan bonus- I've seen Silfy say with good reason that 8 is the magic number in UR. Chiro needs her ability to hit that hard- so doing this in an SoA banned week is a go, but compare them side by side, with all bonuses to make things easy.
Chiro is 8/8.
Isatis is 9/8.
It's a very subtle difference, and it's a choice between reliable damage and reliable power when SoA is incoming (which yeah, then you'd probably want Chiro 's base power), but because there's "no SoA" this week Isatis carries 1 more power than her friend. Give her(him? the bio totally says himself, lol) a good going over- she may not make it anyway, but she's at least worth consideration. I'm totally using Isatis- heck, use her just because she's hot.
.. or rather he. ... Dude, his bio totally says him. It really does. I'm including Isatis just so I can be like MANBOOBS FTW.
I like the deck for, however, I see a problem. SoA week will be flooded with Damage reducers (hence the banning of all DRs the week after), so your 2HKOs could get ruined quite easily, which would make playing La Junta fairly difficult. A really good La Junta deck, just La Junta is going to have a lot of trouble next week (or so I think).
