This deck is sweet. It's a great metagame choice, and has been by far the most winning deck I've ever played. It plays well against both aggro and control, having tutorable answers to both.
Parul's choice is an amazing tutor for a lot of bullets. Avigraft and Caltrops are great answers to many of the best creatures in the format. Grenadin deck? Can't play them. Rats? Can't play them.
Gryffin's win the game. The Soothing Shortbeaks slow down any deck, and are very effective of knocking off Aegis. Forbidden-Rider Outcast is phenomenal. Against control, the damage from Curse of Loneliness adds up. Against aggro, it blanks one creature, and blocks another. Archgryffin Patriarch refills your hand, and Parul Sealkeeper adds both a massive endurance creature, and a double damage flyer that could potentially be huge.
If your creatures don't finish the game by themselves, Kodosh Sees All is crazy powerful. Keep cursing their creatures, stop them from attacking you, and make ever bigger Gryffins ever turn. If they have a big guy, you can block it every turn until you find an answer.
The deck has been performing very well, and it's a ton of fun, but I'd love any suggestions to improve it.
