TailpitsAttack Reimu @ Lum Berry
Ability: Hakurei Miko
Ev's: 252 Atk/ 252 Spd/ 4 hp
Nature: Adamant (+Atk/-SpAtk)
-Tailwind
-High Jump Kick
-Outrage/rock bullet/taunt
-Soar
Dream/flying is an amazing stab combination resisted only by wind/dark (Elis) wind/reason (Marisa) and wind/flying (Aya forms) outrage at +1 adamant allows Reimu to combat the many physically bulky dream types who loooove to run steel coverage and allows her to take on defensive Aya "well enough", rock bullet removes Elis/Marisa from the picture with a bit of spikes damage and picks off pesky blade flash users. Taunt can let you set up to insane levels on phasers/status inducers while running a type boosting item to bypass the need for coverage altogether. The given Ev's out speed + nature base 140 mons and 120 adamant +1 hits stupidly hard. Plus she has solid natural bulk so she can consistently tank 1 blade flash or ice shard and continue sweeping. Oh and flying Stab + Immunity to intimidate = physical sweeper that Rin cannot wall.
Counters: Rock bullet set Potent physical walls can normally sponge 1 hit even after spikes and phase Reimu out, thunder wave her, or OHKO her. Also T aya.
Outrage Set Banded Blade flash will do roughly 76.39 - 90.06%% to Reimu so prior damage is needed to kill. D kanako, D Tenshi, and Yoshika can still phase her out somewhat easily.
Taunt set Reimu's surefire counters are almost all physical walls making taunt a legit option however, D Ichirin, D Tenshi, magic stones and Kikuri can all live a hit and kill off Reimu with ease if she's dumb enough try and taunt them..
. Speed Lilly black can play the protect or boost game and ohko with stab dark pulse if she wins but its just a tad risky.
Support: Spikes turn so many close 2 hit KO's into OHKO's for Reimu and she really wants damage on her counters Sub/Disable Seiga, Subseed SMedicine and other annoyance mons can force switches and traditional phasing can...phase things in order to rack up passive damage quickly and many of A Reimu's otherwise surefire counters have no reliable recovery so status is also nifty. All of this amounts to A Reimu playing a very nice cleanup for both aggressive and balanced/stall teams.
Options: Like most strong physical attackers A Reimu can run a pretty decent band set, 4 attacks band or 3 attacks sleep talk band are both pretty nifty . As always a type item/lefties can be run over coverage in conjunction with taunt for more raw power.
