I'm still opposed to this card. Having an instant kill w/ splash damage is easily far too powerful. Don't bring up the "oh but it'll kill the weak creature and barely do dmg" arguement. The targeting is RANDOM it has every bit as likely a chance to kill the small creature after a jump or two as it does never touching it. Unless your oponent spams small creatures, which would diminsh the effect of this card anyways, this is more likely to jump many times, doing well over 5 damage you get with lightning. I still suggest making it jump a limited number of times while starting with a high dmg and doing succesively less. This has the added advantage of guarenteeing you high dmg on 1 creature and the the bonus jumps, thus the spell is more precise and overall has a higher chance of hitting useless targets. Not to mention you'd be guarenteed those hits.
Ex: Deals 5 dmg to target then jumps for 3 then 1. Total 9 dmg(can be more,less, w/e) Helps apply a standard for balance as well.
Random does not mean equally likely.
In an Extreme case:
22 Photons, 1 Massive Dragon
If all had an equal chance of dying, the Massive Dragon would die 1/23 times
Since it is not an equal chance of dying, the Massive Dragon would die 1/23^30 times
Lightning deals 5 damage to a single target and only costs 2
+ 1 card. Saying something is greatly more effect than Lightning is saying it should cost greatly more than 2
+1card. It already does cost greatly more at 8
+1card.
That said: I do prefer a 5 to 3 to 2 to 1 jump because it is less random and shows the dissipation of energy from jump to jump.
