Heheh. Yes, you could outwit any human player I believe. Most people will play there strategy and just not care about what yours is, or they're really bad at predicting. I played a time deck with darkness mark in pvp2, every player except one out of 12 games just played out all there cards for me to nightmare them. I'm either playing a variant of eggmare or ghostmare. Either way, you know I am going to nightmare. Now, if you get a player too many times and their is a viable way for them to win using their strategy, they will probably kill you. Also you can put a ton pf pressure on someone trying to be smart with the braveries and the healing. Yes pvp2 is where this deck belongs, and bronze arena. Probably silver arena too. Bronze just isn't worth it, so like you said for good reward pvp2. If you prefer, you can -1/2 light towers +1/2 explosions to stop eternity loops and sop. But I am not finding any SoP decks in pvp2, nor eternity loops. But the only person I keep finding is quatertoeleven with a sog rush. Too bad Im not playing this deck currently cause of another deck idea. I'll be posting two decks soon, a death effects sop bow (which will decrease the healing decks wr I presume, of the irony, but if the sopabow gets too popular Ill just throw in the explosions like I said. I'm one step ahead XD.) Another deck being a pvp version of the fg killer I made. Then, and finally, its time to re-test the fg killer for official testing and stats.
Edit: if you feel more comfortable with damage, change it up a bit to have a dragon and an archangel.
