Kiora, Master of the Depths

The ideal win condition is to have Kiora, Master of the Depths use her ultimate ability to clear the board and then throw as many octopi/octopodes/octopuses at your opponent's face so they throw their cards on the table while mumbling "well this was fun" and then suggest an alternative activity for the remainder of the evening.

Doubling Season is the real bling bling card for this deck as it accelerates Kiora's loyalty and then replicates every octopus from her ultimate ability. Birds of Paradise provides a 2 for 1 ramp with Kiora's +1 ability and I threw cultivate into the mix to help speed things up while also thinning out your deck.

T1 = Forest, Birds of Paradise
T2 = Hinterland Harbor, Cultivate (Island)
T3 = Forest, Doubling Season
T4 = Kiora, Master of the Depths (use -8)
T5 = OCTOPUS TO THE FACE, GG LOL

This deck has several weaknesses, particularly board wipes or planeswalker removal since she is basically your sole win condition. Urban Evolution allows you to quickly regrow any lost appendages. Rapid Hybridization and Mnemonic Wall offer you control options for games that don't go as planned. Sagu Mauler is just a BAMF.
