Well, it's not infinite (yet) but I've got a decent team-based combo for massive attacks with Sword of Zeal.

Ingredients:
- Gorebelly equipped with Sword of Zeal, with Heroic Strike and Rak Skyfury in his hand
- Omedus with Wormwood in play and Power Word: Fortitude on that Wormwood

The combo:
1) Gorebelly plays Heroic Strike (Zeal now has 5 ATK) and strikes with Zeal, readying his resources.
2) Gorebelly recruits Rak, readying himself and Zeal and attacks again, readying his resources.
3) Omedus uses Wormwood's ability to send Rak back to Gorebelly's hand.
4) Repeat step 2 and 3 until either Wormwood or Onyxia is dead.

If he has 6 resources Gorebelly can afford to ready any of his teammates' resources every second attack, allowing Omedus (or another healer in the party) to heal Wormwood.

Several cards also improve the combo (reducing weapon strike cost or increasing weapon ATK), but I think this is the minimum required to get some Zeal abuse going.

AHA! While you're readying resources, you could also be using Heirophant Caydiem to heal Wormwood... she might just break things! I'll have to think about that some more.

Thoughts?

Have a good one!

And I guess just one Frost Shock, Frost Nova, or Dudefella would ruin your day eh?

Frost shoooooooooock!!!!!!!!!!!!!!!!!!!

I guess you could use it to get an infinite combo. Against Onyxia it might be a cool way to win.

Sword of Zeal
Heroic Strike x2
Wormwood
Rak Skyfury
Heirophant Cadiem
Power Word Fortitude or Might of the Wild.

Wait Onyxia is a Shaman now eh?

And I guess just one Shield Bash or piece of armor would ruin yours? Seriously, we can play the "I counter you, you counter me" game all day. I know the combo can be countered (as every combo can), I'm just trying to get the info out there so people can think about it and perhaps improve upon it.

Have a good one!

Actually it's totally possible in the warrior deck now. The ONYXIA BLOOD TALISMAN gives all your allies +2 health meaning you don't need those out-of-class abilities to reuse WORMWOOD.
