Smartbombs are great. I love it when everyone, including me, gets caught in the explosion. Smart Bombs can also be used not only for teh lulz, but also as a game-winning item. With high enough damage, a smart bomb can really be a good finisher. Not to mention the fact that it's boom looks downight wicked.
I hate PokeBalls. The concept of the item is great, though most of the Pokemon are very poorly programed. Everyone looks at Assist Trophies as carbon copies of the Pokeball, but
1) The AT opens on spot, while you must land the ball. I can't count all of my miss-ground failures on the fingers of my entire family.
2) AT helpers go and kill my opponent. Pokemon, however, attack thin air and kinda hope that everything works out, while it rarely does. Some pokemon will be, um, slightly smarter than the average rock and sorta follow the foe like Staryu does, but the fact that a freaking Entei won't bother to walk to my foe before making a fire death pillar of doom makes me kinda upset.
Also, someone may have gotten in before me, but blhds, try to use the edit button next time to add more thoughts to a thread if no one posted after your post. If you want to make them like 2 seprate posts, you can hit enter twice and put the second post after this:
EDIT:
See what i mean? Just a heads up.
