Well, never thought that it would do
this well, but it seems you don't really need QTs, Novas, ImmoGolems, nor Shards for a successful Arena Deck.

3x Mark, Double Draw, 30 ups, 135 Hp - Oracle card was Ice bolt.
Peaked at 1st place since 3days now, the coins you see I own is almost exactly the income from the wins of the deck (+/- daily FGs).

So, Water is still underrated? :]
