I can think of at least 1 mon that I wonder why it's no longer on vr too, and now that this thread isn't fully dead, I can ask that in a better place. Arboliva is a great answer to Caly S, Miraidon, and Kyogre. I hesitate to say just check, because typically she can switch in on these too, and proceed to win. The first two there are kinda huge, though Arb is good vs a bunch of special attackers, and can even do leech/strength sap type stuff fwiw. The advent of Alluring Voice really helped, Gleam is ok, but cutting through sub(esp subbers setting up, they get confused,) is key. Pluus there's any number of things that might think they can set up, and assume they will take a lot less if they don't hit to start terrain for the extra power on STAB. Pao and Koraidon are plainly bad for arb, but there is tera and what not...I won't push until and if I get results overall, but I'd still like to know why Arb got taken down, and moreover why she isn't back up in this meta.
