Right, but in most cases you can just play another queen or not worry about it if you get enough fireflies out. One really satisfying thing about this deck is facing an enemy with 2 purple nymphs (in pvp, in my case) and watching him antimatter 2 fireflies only to watch me snipe two and immediately replace them with fresh ones. When this deck takes off, it really takes off. ^_^ If your opponent doesn't have any mass creature control, he's screwed. Speaking of which, owl's eye is extremely useful against many many threats. Against a lobotomizer that's stalling with a dim shield, you can snipe+replace as he lobos, to keep your hope up.
I've been farming FGs recently, but I'll try this deck out and let you know what I think. It looked to me like decking out was a very real possibility against AI5s (AI3s don't require such a complex and strong deck, lol) that drop any number of cards. The owl's eyes are extremely useful for killing your own creatures, such as when you get aflaotoxined+skull bucklered, or if your opponent drops a 4-damage preventing hope (yeah, it happened) with four immortal bio-luminescent frogs (god damn I want one now, I wonder if the pet shop sells them...) so you can clear room for your dragons. The 3 dragons won me many games (out of the ~25 I played, lol) when I won with ten or less cards left. Without all that extra damage decking out would have been a very real possibility. I wish there was some option for permanent destruction with this deck, but the only practical way to go would be to make it mark of fire and pack deflags/explosions. Steals are out since you can't steal shields if you have hope up (you can always replace it with another hope, but eeehhhhhhh, too risky for my taste. Butterfly effect is expensive, pulvy is way out of question. I think I'll try mark of fire+deflags and see how that goes. I can definitely replace drags with angels in that case, but I may be too short on quanta to get the combo rolling. We'll see.
