The casting cost is a little prohibitive, so you wont be playing this outside of a straight red/green deck, but seeing Hugs early is definitely a good reason to try to draft those colors
Your opponents wont be happy about you destroying their permanents each turn, so theyll likely gun for Reaper King or you before it even hits the battlefield
Trigger the ability on your turn, or with little mana remaining and you can lose out on your extra card
So, while Animated Army can bring the pain, you have to be very careful not to get wiped out of the game before you can make that happen
Anything illustrated is counted even if it isn't in the art box
I think the best fodder are ones that replace themselves or have some sort of effect when they enter the battlefield since theyve already provided value coming in, so the body is fine to use going out
