Help Did I miss out on Doomtrain and St-Def items?

[Blockinlick]

If I did, it's a real huge kick in the testes, because I really need "Status Defx4" & "Forbid Med-RF".

I'm on Disc 3 and I'm at the part where we're going back to Esthar to rescue Shana... I... I mean Rinoa [Haha, see what I did there?].

Anyways, puns and RPG references aside, I also need to know if, at this point, I can still do the Card Queen quest... as I've read you can get 3 Status Guards [St-Defx4] from refining Doomtrains card, which apparently can only be obtained during the Card Queen quest.
Without St-Defx4 I might as well just set my memory card on fire, piss on it, and start all over... I know I can get a Status Guard from Shumi Village, but 1 just isn't going to cut it.

Against my better judgement... Assuming you use the standard 3 person party instead of equalizing among all six, you should only need the one from Shumi Village as both Doomtrain and Cerberus have ST-Def-Jx4. However if you're doing the equalization method then the Queen of Cards isn't unavailable yet. Lose the Alexander card to her in a match and then the pub owner in Timber will have Doomtrain in his deck. If you're going for completetion lose Doomtrain to her so you can get the Phoenix card in Esthar.

As for the Doomtrain GF, the ring should be at Tear's point at the center structure. If you can't get into it, you're shit out of luck.
