BR Turtle Patrol
This is a list that makes use out of blue's strong 7s package and then transitions into red's powerfull removal which enables great board clears. You have alot of amazing draws from Gemshell as the overall synergy is quite strong within the deck.
Depending on the meta, you can run a third copy of Frogify, if you'd rather have more hard removal options over a third Seifer's Wrath.
With this build you want to emphasize on your blue creatures and create 4 lakes and make a total of 2 mountains per game. Be very mindfull with your land placement, as the Rakoakopter requires alot of carefull positioning in order to get the maximum value.
I like starting in front of orb, if you can get away with playing the deck midrange.
This gives you some very good lands for later on and allows your archons to charge across the board while double collecting.
Good luck on ladder and happy hollidays from a festive Lizard
