2 bottomless, a mirror force and more icarus attacks would be nice haha. the bribes aren't really needed but i guess that's your choice. i personally don't like giving my opponent more cards in their hand haha
battlestorm, in my opinion, isn't really that good and elphin too (I tried them...haha) and a blackwing deck is pretty weak without the kaluts haha. other than that the monsters look pretty ok
and maybe another copy of armor master and armed wing. and you only really need 1 red dragon archfiend.
i would say take out the gold sarc's but that's probably just a player preference. that's up to you
good job on the deck haha
