You only play 4 Dragon cards (Rhaegal x2 + Drogon + Viserion) and you play 3 Dragon Attack and 3 Dragon Bite… Aren't they dead cards in most of your games? You don't even play Rhaegar's Harp. In melee my dragons are targeted a lot by my opponents effects (kill or kneel) so it's not frequent that I use them a lot in a game.
You play Disgruntled Mercenaries, they're great with Dragon Bite but they are almost useless on board in melee (even with Power of arms), aren't they?
Why play 3 Warlock Servitors? Aren't they a bit expensive?
