[b1000]

ok me and my friend have been wondering for a few weeks now if a Sneasel undauted (68/90) as a special dark energy attached when it use the attack"beat up" witch reads flip a coin for each of your pokemon in play this attack does 20 times number of heads.

so with the dark energy does this do 20 times number of heads plus 10 or does it do 30 times number of heads? thanks alot for any help

The attack would do 20 damage times the number of heads, then 10 additional damage before applying weakness and resistance.

and to add to this, if you flip 0 heads, the attack does 0 damage, even with anything that adds damage.
