1) Your art link doesn't prove you have free use of it. Please link to the source site when it may be proven you can use this artwork.
2) Fix the title, it should read Instant Destruction | Instant Destruction
3) The ungodly cost, while not unrealistic for certain fire archetypes, is something that will be frowned upon heavily. High cost cards are meant to be powerful and such, but this is overboard. Also, why 76?
4) Neither of the present effects will ever be acceptable. Instant win is unreasonable to begin with. And the upgraded free EM will never be accepted as evidenced by Miracle.
I assume you're new to the game and cardmaking, I suggest taking a look around at the rules and then browsing some of the current ideas out there. Browse the higher level polls, they'll give you a good idea of some successful ideas. Then try to find what works for you and the community. Card design is about innovation. You come up with an idea and the community helps you perfect it.
