Don't you just love when a crazy plan comes together? On a very suboptimal draft pick I got Tainted Zealot, Arena Treasure Chest and Star Aligner. The best choice according to HearthArena was the Zealot but I like to have some unexpected options - the whole deck was not the best so a gimmick can sometimes save you. And it did. Game three saved me from a full board Paladin with me at 4 health. He went face with a Dinosized minion and support. One does not expect the Star Aligner ;)
I had something a bit similar happen to me on what I thought was a decent Warrior deck but ended up going 1:3. The last game I lost after regaining board advantage when the Shaman Unstably Evolved one of his Grubs into a Radiant Elemental. It was a fiesta of evolves and me dead in the next round.
I guess I am too calm or calculated for stuff like that. I think I never gave at such an early stage. I sympathize but at the same time I remember enough wild ups and downs - lost matches which seemed 100% mine and the other way round.
I have just experienced one of the strangest Arena throws. Was 4:2 with a crappy (63 point something) Priest deck. My only one-drop is Gravelsnout Knight and I get it going first against a Warrior. He gets a Chameleos, goes face. I kill the bugger, heal the Knight. He drops and Acidic Swamp Ooze. I Power Word: Shield the Knight, kill he Ooze and heal. He... rage quits out. Really? Turn 3, with coin and no health lost? And in Arena?
