For my (upcoming) VGC 2015 team I am using a Ludicolo. You've just gotta love the Carefree Pokémon, and that's why I'm using him. Fake Out support, potential Burns, Rotom-W counter… he does them all. The only thing I can't decide is what Ice attack to use for him. At first I was gonna go Ice Beam like everyone else to slam Garchomp and MegaMence, but as I was scrolling through his moveset page, I saw that he gets Icy Wind via Move Tutor. I don't have any form of speed control, so I thought that he was bulky enough to live without a strong Ice attack. However, it has its downsides. Let me explain:
+) hits common Dragons such as Hydreigon, Garchomp and Salamence supereffectively, and OHKOs the latter two with a little chip damage.
+) is a stronger move in general
+) offers useful speed control, especially for T-Tar and Aegislash
+) allows me to hit tw oopponents, meaning that DoubleDragon leads have to be more wary
+) unexpected, giving me the edge and hopefully forcing switches for the likes of Lando and Garchomp, who don't want to eat what they think is an Ice Beam
-) blocked by Wide Guard
-) not nearly as strong as Ice Beam, missing out on vital KOs
-) gives Milotic the Competitive boost and Bisharp the Defiant boost
So I know that Icy Wind is probably the inferior option, but I think it best to at least consider it. Thanks for your feedback!
