I did alot of test duels with this deck, and I found some things:
Armageddon Knight VS dark Grepher VS foolish burial: I found Armageddon is the best choice because with him I'll send 100% the card in my grave, unlike grepher, because discarding I can't iscard always a dark monster... Armageddon is better than foolish because he's a DARK monster, that mean he's good with DAD or PoC (when I take DAD eff). That's why I chose armagedon, not grepher (I tested this alot). about 3 copies of this card, they are all useful because I need to have some specific monsters in my grave (Metal darkness dragon, Dark horus, DAD sometimes for PoC, and wyvern from time to time). But the best way to send mosnters to grave is Future Fusion (I lost only 1 or 2 times in a duel where I used Future Fusion, despite if I can't Summon Five headed dragon)
PoC, I think it's a very good card, it was always useful?!! I always like this card in my hand, good with DAD and Metal darkness dragon, and return from another D.
I made only 1 copy of Vortex, but after testing, I found adding another vortex is obligatory, because I have a few ways to destroy monsters like marsh and spirit reaper (I have only 2*vortex+DAD). Vortex is very useful to OTK my opp. (my goal isn't to take the control of the duel with BIG atak monsters, my goal is to OTK my opp.!) Vortex help alot when my opp. has the control of the field (it saved me aloooot)
about burial, I'm not sure, maybe you're right. I'll continue testing this card (it isn't always a dead draw, it can save some times, like returning wyvern to the grave and re-using his eff)
BTH is very useful, it doesn't just destroy a monster but remove it from play, specially with Bestiari, and judgement dragon. Also, it prepare the field for an OTK the next turn.
3* D prison... I admit I just add this card because I didn't know what to add in 3 free places in this deck
about dragon's Mirror I tried it and it was the most of time a dead draw, because the most of time I have few monsters in my grave and need them there.
thank's for plaguespreader because I totally missed this card, how did I forget it?????
Gold sarc, I thought seriously about this card, but I didn't add it because I think this card give my opp. the opportunity to anticipate my next move (the most of time my next move will be to OTK him xD), then he can prepare himself to face this... Also it can be a dead draw... Anyways I'll try it.
To face an OTK I'm not very anxious until now, with all this number of traps... but maybe I'll add roar if I see it's a must (until now I was OTK only 1 time, that mean there isn't a big problemwith OTK until now)...
About Royal Oppression I'm anxious, but I have some cards in my side deck that can save in this case (but trap eater is very situational, isn't it?)
But I need to test this, because unfortunately I hadn't the chance to face a real oppression deck (it isn't very used in KCVDS 1.19, idk why????)
well, after this I think that's what I shoukd do
-1 D Prison
+1 zombie carrier
+some synchro in extra deck sure
I need to test how it will work with this:
-1 other D prison
-1 Burial
+1 Gold Sac
+Thratning roar
(I would like to remove all D prisons, but I didn't find until now a card that can take its place
)
Anyways I lose few times with this deck (1/5), as long as the most of people use meta decks, but I don't know how it will work with anti meta decks
Thank you very much neko for helping as always with decks, you're the best deck advisor I have ever seen
