Thieves' Auction is one of the most chaotic cards on the block, flipping games on their head whenever it resolves
And it is projected to grow by 16% annually
A 1/1 for three mana with protection from white and black, Animar gains a +1/+1 counter whenever you cast a creature, reducing the cost of creatures you cast by an amount of mana equal to the number of counters on it
That takes this fairly fair "loot, but not until the beginning of your next turn, and it costs two mana" creature, and pushes it squarely into unfair territory as you draw a card anytime anything comes out of the command zone
