After bearing with the format you put your cards in, I actually read them. Not too bad, but effect monsters don't have in their effects what they fuse with. Also, half of the wording is unclear. Try to write it more like Konami would. For example: Cards don't target Life Points. They either inflict effect damage or battle damage. Figure that out and make the wording clearer.


One more thing, there is no such thing as a 'fusion' spell because all spells that involve fusions are treated as normal spells.
