Ok, so the power level of Deathstalker Rexxar is dubious, but you could create some really powerful beasts! Name your favorite combinations! I like this one: Angry Chicken plus Stegodon = 5 cost 3/7 taunt with Enrage +5 attack for a powerful defensive beast!

Scavenging Hyena + jungle panther

Tundra + Fledger

Stonetusk+fledgling

Gastropod+dispatch kodo

Tundra rhino+young dragon hawk

But angrey chicken stegodon is another cool one I didn't think of

Fiery Bat + Giant Wasp

Duskboar + Dispatch K6odo

Knuckles + Young Dragonhawk

King Mukla + Stranglethorn Tiger

NEW!! Bearshark + Stegadon for a 7 mana 6/9 Taunt can't be targeted. 

For anyone interested I did a complete analysis of all possible Zombeasts. You can see my findings here:

Fiery Bat + Giant Wasp

 This does not work. If you give fiery bat poisonous then it does not kill what it hits with its deathrattle

Arfus + Stonetusk Boar

Trade it and get an OP card in your hand

Rat Pack + Duskboar

Get the initial 6 dmg on turn of play, relatively cheap at 5 mana. Then spawn 6 1/1's on death

I made dis. It was glorious.

BUild a Beasst saved my life against druid when I just shat out big taunts. btw, Blood Worm makes this Hero Power so much better than it already is
