To the >5 thing there was times when i used only my fire dragon (12hp) and my phoenix (7hp) as i just started using the dark gargoyle last night. they was still going through the shield. Now as for the game randomly ending, i was using a 40 card deck vs. a 30 card deck and im a dark-fire sorcerer, so i dont use many cards when my dragons, phoenix, and gargoyles come into play. im talking, i had 72 pts left to his 13. sometimes BEFORE i even click the button to finnish MY turn, it says i loose. I NEVER go past 10 cards left.
