Pokemon HeartGold

[Namine]

Elemental item only gives usually 10% boost to that element's attack, which is usually far from significant enough to make any difference. You almost always want multi-elemental as much as you can and almost never stack attacks of the same element. Consider leftovers instead which heals 1/16th of your hp every turn. Essentially negates sandstorm damage, or if you live 16 turns, that's essentially a 2nd life. Generally, items are usually either choice band, choice scarf, choice spec, focus sash (for leads), leftovers, or life orb. Specific strats may have specialized items like light clay, damp rock, chesto berry or lum berry, but those are the more common ones.

Typlosion is the odd one out since most of them use choice scarf, then carry eruption. But since eruption drops in power really fast if it's damaged (which can happen a lot by stealth rock, or aqua jet) then it carries flamethrower/fire blast as 2nd fire attack. That's another one of those odd exceptional times to use 2 attacks of the same element. Typlosion isn't a good Pokemon to use in "no AR" teams cause you don't have access to hidden power, and Typlosion's movepool is far too shallow to avoid hidden power...
