The Scorpion God

Pretty simple -1/-1 counter deck.
•1/-1 counters; infect; wither; proliferate
• Animate artifacts (so I can shrink them too). There aren't good ways to animate lands or enchantments in B/R unfortunately.
• I tinkered with the idea of using Obosh as Companion, but there just aren't enough good odd CMC cards.
• I suppose one other thing I could've looked at it is creatures with the Undying mechanic, as I can cancel out the +1/+1 counter, but I haven't done that yet.
