Chansey comes in on a magearna that hasn't set up yet. (If you let it setup, you deserve to lose tbh)
Chansey gets to thunder wave and paralyze Magearna, and actually outspeeds magearna once it's paralyzed.
Chansey only needs 4 seismic tosses to kill magearna, so here are a few relevant damage calcs against it.
+3 0 SpA Magearna Stored Power (140 BP) vs. 248 HP / 0 SpD Eviolite Chansey: 201-237 (28.5 - 33.7%) -- 0.5% chance to 3HKO
(At this point, magearna wouldve been hit by two seismic tosses already)
+4 0 SpA Magearna Stored Power (180 BP) vs. 248 HP / 0 SpD Eviolite Chansey: 310-365 (44 - 51.9%) -- 14.1% chance to 2HKO
(Wouldve gotten hit by 3 here)
Not to mention hax :3, this mon solidly counters magearna.
