Just tried the deck in 2 pvp matches, was slaughtered in both.
A note before hand, I don't mean any offense by this, second game I just got unlucky, first game that guy's either gonna get banned for hacking or his deck's gonna get a major nerf.
First game, I only got 1 pillar, and my opponent hacked the game or something, i dont know, all i know is he emptied his hand on the first turn and had an ash eater and crimson dragon out, on the first turn. There was nothing I could do, i had no pillars, he had a huge creature out beating the crap out of me, i was still unable to do anything by the time i was at half health, all i did the entire game was cast one earthquake, on a single pendulum. I didn't even bother playing that game the rest of the way through. Second game, I was playing some guy with a dark/death deck, with a record of like 9/7 or something like that, I assumed he was going to be easy. Didn't get what i needed at all. He had a black dragon out, a vampire, and that vulture thing and over 20 mana in each of his two elements, and i never once drew an earthquake, hell he locked ME down with a single devourer bc all i had in hand was dark cards, and this deck is completely reliant on pendulums to generate dark mana. I didn't finish that game either, not playing anymore pvp with this thing, I lost 60 money in less than 2 minutes.
Oh well, at least this thing is great for grinding the AI. One thing I have noticed though, is that it doesn't seem possible to build a deck that's good at both pvp AND the AI. I actually built some pvp deck I found online, involving nightmares and ghost of the past. Its SUPPOSED to be one of the top pvp decks, well against the AI, that thing's a joke, I assure you of that, even my original mono-dark deck faired vastly better. I mean seriously that thing I built struggled against the lvl 1 ai.
