Can we just talk about this card for a moment?
This card is wonderful if you have an energy synergy in your cube. It is so much more than what it initially seems. It's a strong, potentially undercosted beater that (and this is key) -also- functions as a T1 utility play in the deck that wants energy! That makes it much more flexible than it initially seems to be. It also easily triggers ETB effects multiple times, with careful energy management. Otherwise, it's GGG (that you can pay for in parts) for a 3/4, which is a reasonable cost.
It's rare to see a card that allows truly creative deckbuilding, but I could see this going in blink, energy, aggro and even more archetypes. It functions as a T1 play, and allows you to 'invest' in it when you need to fill out your curve. (akin to
student of warfare) It's a cheap sac outlet (you can sacrifice it with it's own return trigger on the stack... and crew vehicles as well). It triggers other ETBs. While I'm not 100% going to jam it in every cube I make, I do think that overlooking this card entirely would be criminal.
What do you guys think?
