Fire emblem is great
I just wanted to be absolutely clear on this:
Will damaging weather conditions (Sandstorm, Hail) remove Double Team clones from the field? What about if the Pokemon is a ghost-type that does not resist the weather?
On most ref's scales, yes, damaging weather will remove double team clones from the field unless the pokémon in question is immune to that weather condition (e.g. sandstorm will destroy a Normal Type's clones, but not a Rock-Type). But it varies, so just check with your ref first.
Also, I've often seen commands such as "spread out Flamethrower if there are clones". Are there some guidelines on which moves can and cannot be spread? Can beam attacks be used in the same way?
Mostly it's based on flavor, I think. Flamethrower is an attack that, by the nature of being a drawn-out stream of fire, can be waved around. Something like Thunderbolt, Ice Beam, or Fire Blast - instantaneous attacks that come out quickly and with a very limited range - couldn't be able to be used in that way, although a pokémon could theoretically be able to angle itself in a way to hit two clones instead of one with the attack.
