Yes, that seems all right. I had five test runs. True, against False Gods, not Arena decks or anything like that...
1. Divine Glory: He stood no chance. In the first several rounds, he could take me down to 52 HP, but that was the end - the Dissipation Field soaked up all damage, slow outdeck victory.
2. Octane: No question, this deck was squashed. Despite my effort to use Improved Steal to steal his Unstable Gases, I lost.
3. Ferox: Humilitating defeat. This one had taken me down to 22 HP by the time I managed to get a Dissipation Field out, but the Jade Dragons broke it early.
4. Lionheart: Nearly won. Although he endowed Eternities and put Quintessence on the Crusaders, he put that on pretty much everything else, making it worthless. Even after halfways I had 100 HP, but suddenly he managed to broke the Dissipation Field and one round was enough to take the 'invincible' down.
5. Dream Catcher: Same story as with Lionheart.
Won:lost ratio was 1:4, which is still better than my currect deck's ratio against False Gods, but I think it isn't worth the effort.
