Flip Coin and Summon Spirit Sphere

[Frogboy]

either it is a bug, or it is because it would interfere with their "coins".

even though both the spheres and coins would do the same thing, i think they are still separated in the coding, and such that you can only have 5 souls and 10 coins, it would be rather a pain to set the right amount of coins for each soul is +3 atk, and each coin is +3 atk. but meh like i said i am satisfied with the answer given about its workings.
