>>33410550RR is dead in standard more or less due to no sky field. You need Volc/Galvantula/Bisharp and a Xerneas benched to hit the numbers you need (you can still hit 240 on turn 2 if you get a perfect start but the conditions for that are way rarer). Consistency is a massive issue, the deck was always shittier than megaray because of that .
You lose a lot of the old tech cards that made the deck successful like Flygon-EX, Genesect-EX is particularly annoying because ever since tool removal came back you can't protect your float stones to prevent getting lysandre fucked which is very common in this deck due to the large number of basics you need to run.
RR is actually pretty good in expanded with Darkrai though. It's very hard to keep the bench down with Darkrai/Eggy/Ho-oh all pulling themselves from discard. Even if they parallel you (and nobody runs that card anymore) you go down to 3 types on the bench and pull the others back up to get back to 6
