Spider Bomb is not the most important card to keep but if you don't have anything better keep it because it might help against both aggro and control. When you already have it you might also go for Fireworks Tech.
Cards that might be included:
Goblin Prank - Easy way to trigger deathrattle minion
Corpse Widow - good stats and effect can make this deck faster
Necromechanic - can give you more value from deathrattles but it's too slow
Cairne Bloodhoof - another great deathrattle card
Blood Knight - Divine shield? not any more...
vs aggro: Fight for board control. You can focus on going all in on Devilsaur Egg plan or stick to removing opponent minions with Candleshot and Spider Bomb. Hunter don't have many ways to heal but Deathstalker Rexxar will provide you everything that you need: +5 armor, Board clear and hero power that can give you Lifesteal minion or taunt. Zilliax can be attached to mech or played alone to provide a little bit of healing and give you more time.
vs control: you should win most of those games. Just focus on getting a lot of value from deathrattle minions. Remember to play around board clears or things like: Polymorph, Hex and of course Silence. When you will get Deathstalker Rexxar just use hero power every turn.
