I would add extra loud speakers and a new paint job.
Anyway back to the task at hand. I would personally change Eloxia to Tomas as this gives you 1 more power and stop opp: bonus (though you lose a damage buy with Berzerk that dosn't really matter).
I would keep Sasha because even in a half deck shes still the second best 2* Skeelz after Redra (they swap places in mono decks).
It seems a little top-heavy. Even though Eloxia has nice synergy with Berzerk, her use in this deck seems a little predictable... Why not swap her out for Greem? Drawing a "heavy poison" card along with a powerful wall creates a huge threat for your opponent, and the poison will usually help you win the game if you can land it in any turn 1-3, as long as your wall has round 4 covered. Use your extra star to fill out your deck with another strong card -- there's so many to chose from, I won't even bother listing them.
