Unlike her normal and helpful alter ego's AStar Sapphire isn't afraid to get up close and physical, with a startling 120 base attack stat and a suprisingly potent dual stab combination. Tack that onto the hefty support movepool that she shares with her more defensive forms and a very respectable 90/80/80 bulk and AStar can be quite the threat as her combination of typing and movepool allow her to check or counter a pretty insane range of tippy top tier threats all on her lonesome.
Set: A Bloomers SapphireAttack Star Sapphire (M) @ Special Bloomers
Ability: Water Absorb
EVs: 4 HP/252 Atk/252 Spd
Adamant nature (+Atk,-SpAtk)
- Aqua Jet
- Ice Punch
- Power Whip
- Sleep Talk/Baton Pass
Bulky thing with priority? Wynaut band it? Max attack and speed ensures that you will most likely outrun even anti speed creep base 60's 70's and some 80's while smacking the unholy hell out of them with AStar's quite decent coverage. So pretty standard bulky band. The last move slot is what gives AStar her own semi unique niche though, sleep talk allows you to give those annoying sleep powder and focus hypnosis users a truly nasty surprise while baton pass allows for pseudo U turn backed up by the threat of a banded aqua jet.
Set: A Swimsuit SapphireAttack Star Sapphire (M) @ Swimsuit (Water)
Ability: Water Absorb
EVs: 84 HP/252 Atk/172 Spd
Adamant nature (+Atk,-SpAtk)
- Aqua Jet
- Power Whip
- Recover
- Waterfall/Ice Punch/Baton Pass
Unlike AStars choice set this stylish swimsuit concoction allows Star to "gasp" change her damn move while still powering up that lethal aqua jet, acting as a decently bulky pivot, and even bluffing choice to deadly effect. Max attack swimsuit aqua jet can still fill most if not all of your revenge killing needs while power whip just plain hurts everything and is capable of completely erasing any TToyo's who dare to stay in when combined with the speed creep tastic 172 investment. Recover along with a minor Hp investment allow star to take hits like a champ and the last move is simply a matter of personal preference. Waterfall hits for a nasty chunk of damage when combined with STAB and a swimsuit, Ice Punch nails annoying natures and flying/faiths aiming to wall you out or take advantage of your "choiced" aqua jet and baton pass allows for conservation of momentum.
Set: A Passing SapphireAttack Star Sapphire (M) @ Leftovers
Ability: Water Absorb
EVs: 252 HP/8 Atk/76 Def/172 Spd
Careful nature (+SpDef,-SpAtk)
- Aqua Jet
- Baton Pass
- Power Whip
- Substitute/Jamming
Ok, this set may seem weird (because it is) but I swear it works. Aqua jet and power whip are obviously standard fare at this point the offensive presence they provide is probably the reason your running AStar. However the focus of the set leans more towards passing either substitute or jamming to a team mate to allow for general sicknastyness. The EV spread allows for AStar to fill her typical roles of checking TToyo, APatchouli and revenging with jet while always keeping her sub on any unboosted resisted hit physical or special while also avoiding the 2 hit KO on any unboosted neutral hit and the ohko on any unboosted non 4x effective SE hit.
Support: AStar requires pretty minimal support. Just slap on a steel type or 2 to soak flying and miasma hits and a few mons that like to get a free turn (or 2 or a few hundred depending on what your passing) Spike support can push a few borderline aqua jet ohko's over the edge but sans that AStar is pretty damn easy to slap on a team. Though its worth noting that if AStar picks up either attack or speed boosts she becomes a pretty massive threat allowing her to play pivot "sweeper" for baton pass teams.
Options: AStar has a pretty rich support move pool, hypnosis, barrier, encore, lock on, lucky chant, and even mana charge all make a decent showing while her attacking move pool can allow for some surprise lure killing on DAlice and other water/natures with body slam and poison bomb.
Counters: While AStar can be effectively checked with just about any flying or miasma mon Nue, HEirin, and DHina stand out as the all stars of shutting AStar down as they take virtually nothing from AStars hits and can wreck havoc on quite a few of her favorite pass targets. AStar also has issues revenging annoying faith sweepers such as TByakuren, the Miko forms, the Yorihime forms and normal Reimu.
