Grinder indeed. Used to represent a fundamental pillar to me in how BF was different from any other strategy game I've ever played. You don't get to see 10 m tall Axe-wielding stone giants nowadays in your average RTS game anymore.
Pretty good if used with Nasty or Ethereal Storm, but as @Chimerae said, pretty useless outside of rPvE or if not used as a niche mechanic. There are other better cards to use that slot in a LS deck though.
A really good deal for short PvP games, if you can get enough power it'll definitely be awesome, but sometimes outclassed by S/M T2 cards spam and splash factions too (Lost Shade / Vileblood for example).
You have to play it because it's badass though
Wish granted, but aliens invade us and now we have no means to retaliate against them without the help of an army.
I wish I could have infinite spaghetti.
