Nice deck! However, I think it can be optimized:
-1x Youthful Brewmaster, +1x Void Ripper. Requires less setup, as brewmaster requires you to have an activator in hand or on the board. Also, bouncing minions like sanguine reveler, ratcatcher or ravenous pterrordax is not that great because they will lose their buffs.
-1x Marin the Fox, +1x Scorp-o-matic. There will be enough gifts on the board already, no need to generate an extra one. Besides, 8 mana cost is quite high, you'll likely never be able to play it.
-2x Corruption, +2x Power Overwhelming. With corruption your opponent can kill it's own gift before it's your turn again. Besides, PO is more proactive, as you can use your buffed gift for face damage or trading.
-2x Dark Possession, +2x Grim Rally. You need 2 dark possessions to pop a gift, and you'll likely not have both in hand at the same time. Besides, grim rally is more proactive as it buffs your board.
-2x Voidwalker, +2x Acherus Veteran. Better to buff your board than to protect it I think. The biggest weakness of acherus veteran (in ranked, casual and arena) is that it is a 1 drop that's not good on turn 1 because it can't buff anything. The brawl solves this problem because you'll always have a gift to buff in turn one.
Other than that, you can look at adding cards like Lance Carrier, Defile, Spirit Bomb and Kooky Chemist or running 2x Doomsayer and no Shadowflame (or vice versa)
I've put it into a spoiler because it's quite the wall of text.
