I get what you're doing, but let's look at this from an advantage perspective.

The card is instantly a -2, you discard a card and lose this. Then at the End Phase, you can give yourself an additional -2 for the monster, a +1. So in the end it's just a big -3 that eats up your hand.

Not only that but Felgrand's effect (which I'm assuming this is for due to the title) requires you to tribute a Dragon when it's Summoned from the Grave. So now we've got a -4.

I like what you tried to do, but I honestly don't think it worked very well at all because you made the card exhaust a ridiculous amount of hand advantage.

I can't be sure but I think Felgrand targets a monster in the grave for it's effect. Although the rest of what is above is true. I suggest changing "banish 1 Dragon-Type Monster from you control" to "banish 1 Dragon-Type Monster from your graveyard". That way, it's not such a disadvantage and ties in with a certain dragon that has a "when banished" clause. (I can't remember the actual one.)
