You can actually use the deck your using right now against T50. It'll put up a fight against some of the "real" decks there and there's always a chance you'll come across a farm deck, which usually leads to weapons/shards/rare card in the slots and a elemental mastery.
- Good piece of advice. I got 2 Eternitys, 2 Pulverizers, 4 Morning Stars, 4 Miracles, Owl's Eye, Fahrenheit, Titan, Arsenic, 2 Druidic staves, 2 green shards and 2 Relics from the altruistic members of community who put up farming decks. Now this is starting to look good.
