It might well be too narrow for the cube having only really one home but I would still expect it to get more play in constructed decks than it has (which is also none)
However, despite the small set size, there are plenty of cards that are very valuable and will cost a pretty penny if you want to obtain the fanciest versions available for the cards
But give me a proactive Moonmist that also lets me push damage through with a creature and draw me a card for my troubles and you've got a deal
The -2 is okay, protects the 'walker, has synergy in Beast Tribal, and Populate decks
The biggest drawback is timing: you still need to survive long enough to cast it on turn two
Taurean Mauler $6.99 I dont think its a stretch to call Taurean Mauler the best red shapeshifter, and one of the best typal support pieces for red decks that dont access blue
