As someone who's been religiously laddering for VGC 2017 I can say that it's far too heavily threatened by a number of common things to make the splash you desire, at least in the current state of things. Consider:
Tapu Bulu's Stone Edge and Rock Slide
Anything from Nihilego
Garchomp's Rock Slide
AV Mudsdale's Heavy Slam
Celesteela. Just gonna leave that there.
Kartana's Smart Strike
Torkoal's Eruption following an After You from Lilligant (something for the OP to try btw), or in Trick Room.
Trick Room.
Aerodactyl's Rock Slide (130 Base Speed sir)
Arcanine
Alolan Marowak
Scarf Krookodile's Rock Slide
Less popular but just as threatening:
Salazzle
Gengar
Lycanrock
Gigalith
Wishiwashi
Alolan Sandslash
Alolan Golem
That's a massive threatlist, just off the tippy top. Seems like a high risk/low reward Pokemon, however fun it may be.
Ohhhh boy here we go, you've changed skyberries.
I'm not saying "Ribombee VGC; Ribombee OU; new meta new meta" - the thread is asking for suggestions for a multi team for
battle tree; I'm offering a solid and fun mon that has lots of team play viability and interactivity between players doing a cooperative multi run in battle tree.
Are the Ultra Beasts all that common in the multi battle tree? Does the Muddsdale you see in battle tree have an assault vest? Is there even a krookodile in battle tree, and is it really running Scarf? I see you've also disregarded my correctly noting that -
with 124 base speed - it's definitely outspeeding anything that's not aerodactyl on the punch there.
and furthermore, if you consult the OP -
Planning on going multi with a friend at the battle tree (For the 50 streak battle stance) so first off:
I need some suggestions for a good pokemon that uses moves like Reflect, light screen, safeguard, etc.
And second I need a good pokemon can put some decent hits out while also supporting my partner whether it be buffs, status heal, or things like helping hand.
Any and all suggestions please~
I'm responding to that, and while I am most excited to hear of your VGC success, and consequently extensive knowledge on the newly formed meta, I quite frankly am not quite sure that we're responding to the same thing here my friend.
