1st of all you disconnected while redgar was having a clear advatage. 9 vs 4 while you had 3 lv 6 cards in hand, a useless trap and an 700atk monster. If it is like this everyone disconnects when he is gonna lose and demands a reamatch till he wins. I don't know if you have played in wars before, but you need to know cheating is not tolerated like it is in tournaments. I have in mind you d/c many times in many tournaments , even here in SDA . It is a little difficult to happen every time by chance. If it is then go check your connection.
Secondly, you are lying. His LP was above 3000 when you attacked, redgar explained me the situation. And even if it was so, it doesn't mean anything. A deck is 40 cards that are based around a strategy. We can consider a deck , a burn deck , if it is strongly based around on winning the duel by inflicting burn damage. Caius, Magic Cylinder and such cards have effects that cause burn damage but aren't based on defeating the opponent themselves
