one of the rule, pertaining to adding regular TCG cards, mentions how attacks work. It basically states you only do the base damage, ignoring effects and modifiers (so SV Garchomp's 2nd attack would simply do 120 for 3 energy, ignoring the minus modifier). Now, I know this will mean ignoring damage counter placement attacks, like SF Gengar/etc. But what about "sniping" attacks like AR Pikachu's Mega Shot - do you just classify it having a base damage of 40 atk and follow the rest of the Rumble rules determining attack target etc. Granted the basic Rumble rules also state that you can add your own rules, incase you'd like to add the effects that include coin flips.....
