Hmm... I liked the "Regret" and "Insult" abilities I read about earlier, as well as the ability that randomizes the user's ability each turn. Additionally, earlier I also had ideas similar to that ability about Psych Up+Trace - that's what I envisioned Zoroark having as an ability, to represent his illusory talents.
There are several other nice ideas here, too! :)
Personally, I'd like to see an ability that simulates the effect of Foresight, Miracle Eye, and Odor Sleuth - allowing a foe's immunity to be bypassed, regardless of type(s). Since we have Mold Breaker that correlates to abilities, I figured this is permissible as well.
This is sort of off-topic, but I'd like to see evasiveness play a bigger role in Pokemon battles - possibly via the effects of new abilities. Yeah, I have an anti-"Double-Teaming Blisseys" stance, but I'd still like to see the stat used in some way, instead of its only mention being "it's banned by Smogon!!1!" in forum threads constantly... I mean, 1HKOs, I can understand banning, because it takes no skill to really use them. But just because you're annoyed by a certain stat's usefulness (in this case, evasiveness) doesn't mean it should be outright banned. :\ Yes, Double Team aggravates me to shreds sometimes. :cer_pissed: But I love the challenge that comes with overcoming any opponents who happen to incorporate Double Team in his/her strategy - it makes the eventual win so much more satisfying. ;) :cer_boogie:
