Played rogue yesterday with a deck from the previous arena cycle (not the one which started yesterday). Went 12-1 with it, Score was 71,1. Didnt really expect to get 12 wins since the deck didnt seem that good to me and I only achieved 12 wins once before. I was quite lucky that I often went first and had a good early game. (And I was able to punish my opponent with Missle Launcher + Plaguebringer combo when he didnt trade).
Usually I feel more confident with Mage, I dont like rogue at all (doesnt matter if Arena, Standard or Wild) but lately Rogue was always top class in Arena so I simply always played Rogue when possible and had amazing results lately. (5, 3, 7, 10, 9 Wins in July with Rogue)
And the next 12 wins with a mage drafted on the first day of the expansion on my second account. The Leyline Manipulators in combination with all the discover cards were really disgusting. Zephrys did also a very good job.
12-0 with an insanely strong hunter draft. The 2 Scarlet Webweaver in combination with the other big beasts were almost everytime the game winner. 2 Times I pulled of that a Webweaver reduced the mana of the other Webweaver who reduced Rhino to 0 and I developed 12 burst damage in form of 2 5/5s and 1 2/5 for 7 mana!!!
