I was not expecting to go 4-0 with this deck. It felt like the best I could do with my pool, though maybe I could have done something with red. White and blue had 9 creatures total between them, including the blue/white creature; literally only 4 creatures each. Red had some decent removal.

Overall, I definitely got somewhat lucky to do so well, but the deck was also pretty consistent. The +1/+1 counter synergies were actually pretty strong. Winding Constrictor was absurdly potent.

Also, for the record, I'd only had maybe 2 hours of sleep.
