I think I like this card as almost a 'backup Tinker' in a way. Sometimes you need redundancy in effects, specifically these type to cheat fatties in play. It's a little tougher than Tinker to get to work at times because it needs to be in your hand. However typically when you draft those style of decks you will have 3 or more 6+ CMC creatures which significantly ups the potential of this card being good.
It can't go in every deck, but I think it has huge upside if built around well
