Cards I really miss in this book are 1x Bear Strength and 1x Dancing Scimitar.
Bloodwave Warlord with Vorpal Blade / Morning Star + Spiked Buckler + Bear Strength + Scimitar can roll up to 16 dice per round. Add a Hurl Rock QC and you're rolling up to 21 dice in one round with your Mage
alone.
With your weapon and shield slots filled, I'd remove the Elemental Wand and just replace him with another attack spell or 2 more Hurl Rocks.
As useful as it may be at times, you just don't want to see a Wand of Healing in the Orc's hands.
I'd suggest to find other ways to remove annoying conditions. Clear Mind, Geyser, Raincloud etc are options ... You already have Purify.
Skeletal Knight at 6 sbp's is too costly imo. I'd rather have 1 ( or 2 if you prefer ) Iron Golems instead.
Makes your Retaliates and Battle Fury's better as well.
I guess Gurmash is an OK choice to cast Command Enchantments, but there just aren't enough of those to make him shine.
Playing Command Incantations through him is like letting your opponent listen in on all your play-calls. There's no surprise there and unless your opponent has already run out of actions for that round he always has at least one action to anticipate what's coming. Incantations are simply much better when they can have immediate effect and Gurmash can't give you that ...
General's Signet Ring may not be worth it.
Costs 3 mana and you have only 6 creatures, so a max gain of 3 mana if you cast ALL you creatures.
To increase your Buckler's effectiveness ( and also the Scimitar's ) I suggest adding a Defense Ring instead.
A Bloodwave Buckler book may be the one book where a Defense Ring is worth playing.
I like the Gauntlets of Strength but I think Champion's Gauntlets are the better choice here.
Mend ?
Imo, if you have to start Mending, you're losing.
I really don't think the Orc can afford to waste an action on that.
If you really want a cheap healing option I think Vampiric Strike can offer you more than Mend.
With your 5 dice basic attacks ( and possibly 6 dice basic attack if you should add a Golem ) it may be worth it to add a Whirling Strike. Suddenly rolling 18 dice instead of 6 for 9 mana might take a few by surprise.
Success.
