Let's say you're against control and can get all the armor you want. What then? You get a random 10 drop. Wouldn't you have rather included the threat you wanted in the first place?
Now, you're the defender. Why does this card matter? If you're on turn 6 against an aggressive deck and have enough armor to get this card, then you already won. Regardless, spending your turn getting a bid dude that doesn't do anything specific against aggro would be a bad play.
The only deck this card would fit would be a high-tempo midrange sort of warrior. Would such generate enough armor by turn 6 consistently? I wouldn't think so, not without support.
IMO a more comparable card is Forbidden Shaping, which saw some play. Similarly, you have control over what mana cost minion is summoned, and depending on the cards in the available pool, I'm sure a certain mana cost is going to be the optimal play which you're trying to set up.
I don't see the Forbidden Shaping comparison. Seems like a pretty bad comparison to me. Forbidden Shaping on Turn 6 will get you a 6 drop. This can get you a 10 drop. Forbidden Shaping on Turn 10 will get you a 10 drop. This on Turn 10 can also get you a 10 drop but leave you 4 mana leftover to do whatever you want with. Of course, Forbidden Shaping can also be played prior to Turn 6 if you're desperate to fill out your curve with a 4 or 5 drop....The two cards just aren't very comparable.
Dead card against aggro decks 99% of the time, better off putting an actually strong minion in your deck vs control because you'd be guaranteed to have it. Seems like a really really bad card to me for 6 mana.
I find it interesting how you can manipulate your armor to get what you minion you want. Say you’re at 8 armor and you need grommash to get lethal or to kill off your opponents minion, then you don’t hero power. But say you ran deathwing, (bad example because there’s not many good statted 10 drops) you could hero power to pull him out for the stats.
If I read it correctly, it doesn't recruit a minion from your deck, but rather summons a random minion like Geosculptor Yip ,so it won't work the way you describe it .
6 mana for a random 10 drop seems fine. Not amazing, but probably OK. Better in fatigue than Gather Your Party, and GYP is going to rotate before too long, anyhow. Two of these and Yip could be fun, but probably not the most winning deck.
4 mana remaining isn't a massive amount, but it'll be possible to play it along side stuff. Forbidden Shaping didn't let you do anything else with your turn.
While I think this is kinda fine on it's own in an control warrior, I'm not super enthusiastic about the prospects of non-Odd control warrior. I guess there are some folks who use it. Probably wouldn't be that bad in something like Zamos' Thousand Armor, but I just don't see the hypothetical Heavy Metal deck being top-tier.
