@Misk:The complaint about the trump card is more about the awful setup than that the existence of the trump card being an asspull. I mean:
 * As far as raw power is concerned, Gray's trump card even approaching the level of Natsu's would be BS.
 * There has been no indication that Gray could even theoretically negate Zeref's immortality. And, no, Memento Mori is not an option. It's only an option for Mira.

So... what exactly is one supposed to expect? The only ways it could be effective are clearly BS, so no plot twist will be able to save it. And if it is ineffective... it's something we all knew and expected, so how is it different from Invel's Divine Raiment? ...Maybe Mashima is going for some poetic justice here...

I'm pretty sure Natsu has solved the seeds problem and I'm actually fine with that whole thing, just like I was with Erza stopping Gray vs. Natsu. The problem is that Gray doesn't realize this, so he's clearly not attempting to kill Zeref. Yet he's going to be using his TC... why? To steal the Tome of END? *shrugs* It just makes the situation even more absurd, imo.

@anon: lol, I thought I was pretty subdued this time as compared to previous outbursts. :P And I complained about Mashima's portrayal of Gray rather than Gray himself...
