Thanks I didn't know I could re-do it.
What if I maxed out Iron Defense, then used Baton Pass?
Then if I used Power Trick, the 559 Defense Stat with the +6 Boost will switch to its attack stat? If I maxed out Iron Defense, then that's 300% more than the original stat. 559x3 is 1,677.
So then Shuckle would have an attack stat of 1,677?
Is that correct?
If you mean power trick, it doesn't affect iron defense boosts.
Note that the source uses swords dance, but it should work the same way.
