wanted to post my thoughts on this after seeing another review.
this card is 100% a 5 star (claw? fang? used to be cog?) card in a recursion deck.
stack the deck with khapra's, warpspawns, prime pressence, adren ...... lots of cards like that. some spirit gates and/or palace of bones and lots of draw you can now get your big legendary on your opponents end phase giving opponent less time to respond to it and at a cheaper cost. and a couple grave diggers so you can refill your deck if needed and you're golden.
outside of a recursion deck i see this card as almost unusable i'ld give it 1.5 to 2 fang?
A weapon straight out of batman's repertoire. This nifty little gadget will constantly deal dmg to your opponent's cap, and the more creatures you have deployed, the bigger the punch. I really wish this attachment was a neutral one, because it would definitely be included into all of my decks
It looks tempting....a territory that provides 2 resources. Especially in the first few turns of the game. The downside is that it is unstable, so it is possible that your quick start turns into a disaster. Do you like to gamble and feel lucky, then pick this card. Otherwise leave it be......and that is what I will do.
