The edges between the outer edge and the swirl design are clear on a real card, but on a fake they can blend together because the colors are too close, or the printing quality is low
Personally I think it's the cost on its tap ability that kills it
This is a fairly reliable way to generate energy turn after turn, ensuring you always have a little lying around
not only does it cost less mana than LabMan, but it doesnt require an additional effect to draw a card, and killing it in response rarely interrupts the win since the trigger goes straight to the stack
However, Song of Totentanz is probably going to be the best card in your deck
It fits any curve very well, can block and up trade with larger creatures if needed, and provides incredible board presence through removal or Wrath effects
