So I've finally gotten started on testing things on the side. Let's start with Infiltrator (Which is still listed as Slip Through on the first post)
Infiltrator DOES work with:
Mist (Tested this in double grass on wild Vanillite at Cold Storage, using skill swap (From Reuniclus) on an infiltrator Whimsicott, then using charm while mist is up.)
Infiltrator DOES NOT work with:
Lucky Chant (Tested this in double grass with a skill swap chain going Whimsicott -> Reuniclus -> Throh, then using lucky chant on my own team and using Throh to use Storm Throw on... loads of my team, really. It didn't critical until after lucky chant faded.)
Wide Guard (This is more of a clarification from Setsuna's post. Tested this in double grass with wild Mienshao at Route 14, and an infiltrator Cottonee with Razor Leaf. Mienshao used wide guard the first turn, and Cottonee's Razor Leaf did not hit Mienshao or its partner, with notification that Wide Guard protected them.)
Endure (Tested in double grass using infiltrator Whimsicott against my Victini. It "endured the hit", as it said.)
Gonna do some sky drop tests in a bit. Which reminds me, I noticed the first page hasn't been updated since the end of last year. Is everyone who's able to update it busy with something else?
EDIT:
Okay, Sky Drop tests!
First off, Sky Drop actually damaged an opponent under the effects of telekinesis and under the effects of magnet rise. The former was tested in some double grass (Since telekinesis wore off when I did it in a single battle) and I had to enlist some help for the latter through a wifi battle.
Secondly, Smack Down provided some interesting results. When used on a levitate user, it allowed Sky Drop to hit. However, with a flying type, it still didn't do damage.
Can anybody test Freefall in Rotation Battles? I recently saw a Battle Recorder vid where a Wargle picked up a Kojondo with Freefall, but then Kojondo was rotated out, both Pokemon came down, and Kojondo took no damage.
This... is exactly what happened. Both at the Rotation Battle house in Opelucid City (Black) and in a wifi battle.
