It can pull ANY mech - it's not limited to mechs with death rattles.

Its number one use will be generating pure disappointment when you open it in a pack.

I had forgotten about the pinata and spark drill might not be bad

I wonder if you could combine with Flark's Boom-Zooka somehow?

 Deby downers all ready the one words u know is dust. People like you make me sick.

Name a more iconic duo: Hunter and bad legendaries.

This card looks like hot garbage (especially with the rotation of Play Dead and Terrorscale Stalker), but the rest of the set could reveal something possibly.

No play with Feign Death and Terrorscale rotating.  The fact that this is 6 mana, do nothing on your turn with a weak body and no easy way to get the trigger off is too big a tempo loss.

Now, that doesn't mean they could print a bunch of support cards to make deathrattle mech deck viable, but most likely if they print those cards, this card is along for the ride in the deck, rather than defining the deck.

10 mana.

Oblivatron > Skater Bot > Rush into a minion, pull Mecha'thun > Hunter's Mark on Mecha'thun > Arcane Shot on Mecha'thun

Is it good? Almost certainly not. But it's worth pointing out.

Based on the cards we currently have, this card is a dead card. But if mech hunter gets something big and defensive (like a void lord, for example) then this can be good. Until then, it's a naaaah card.

I am actually playing a wild even shredder deck where this would fit perfectly

 Sure, just need to not draw it and have a decent mech in your hand, i hope blizzard doesn't let this cards as the only mech synergy or one of the 2 unique ones like they did with hireek and the spirit of the bat for warlock in rastakhans rumble, it would be a  horrible waste of card slots

Why are both ‘Maybe’ and ‘Not Sure’ an option in this poll?

 Lmfao

So Guy it looks really disappointing but don't think about death rattle Think about the tempo, You put a couple of big mechs in your deck and you can turn 6 play a 3/4 and a 10/10 meca thun or a 3/4 , 2/2 , 7/7, 7/7 with the mechanical whelp combo. Niche card but has potential to be strong in the right meta.

I think it is a bad card to disenchant. Currently there is not an obvious strong option to cheat out. But that could change at any time.

Hell, this card is only 1 mana from a mecha C'thun combo currently (maybe even possible if there is something I haven't thought of). 

Definitely wouldn't write this card off even if it is not played during the first year after release.

Edit: Worth noting the "and activate it deathrattle" should be seen as icing on the cake. If a high cost taunt or rush mech is added then this could definitely see play similar to Voidlord did with skull.
