How is this a good card draw engine for aggro pally? It can't be played in Odd Paladin, it can't be played in Even Paladin if the 1 attack minions cost 1 mana (like Righteous Protector and Argent Squire). It's terrible tempo. Only if it summoned the minions instead of drawing them, like a mini-Call-to-Arms, would it be viable in aggro.
But in Mech Paladin, this card is at least worth considering. It can draw two Upgradeable Framebots, or maybe some decent 1 attack mech minions that haven't been released yet. It's still terrible tempo, but at least it allows for possible recovery following a bad mulligan.
Even if its a lesser version of Small-Time Recruits, don't underestimate that mana cost of this card, because drawing a specific thing for lower mana cost is much better than what you think, this card can draw and thin your deck much faster than Small time recruits, and can curve very well with Tar Creeper or Stonehill Defender but it makes your turn two play nothing on the board or not summoning your dude however, it seems you can make a choice between drawing or making a 1/1 based on the situation so think about how to use this card wisely.
I can see in a world where this card will be used in most paladin decks either aggro, midrange or control. I expect more 1 attack cards to be featured in this set and have powerful effect maybe.
EDIT: i didn't notice that Small-Time Recruits says one mana not one attack but it feels like they are similar yet underrated...but who cares this card feels amazing to me but not that much.
