Raptors Everywhere! (Standard)

The strategy here is to try and explode with a billion polyraptor tokens by having a marauding raptor on the board before you either cast polyraptor or use the arkbow to cheat it out in your end step with the help of wilderness reclamation. To avoid a forced loss, only let the raptor onto the board if you have a lightning strike or jaya's greeting in hand and enough mana left over to cast it and kill the marauding raptor, OR you have a forerunner on the board. Hold back the forerunners triggers until you have enough raptors. Ranging raptors for a massive mana boost, ripjaws to help you find what you're looking for and fiery cannonade to keep the board clear of weenies while you get set up (and to make more polyraptors, that's a fun surprise if your raptors are all tapped).

Sideboard: Fry for those pesky teferis, narsets and ashioks. Cindervines to help against phoenix/drake and rdw if they're frenzied, domri for control and veil of summer to help protect your guys against decks using removal spells. The strategy is prone to board wipes, if you encounter this, use your emergence zone for a wilderness reclamation charged banefire instead.

Enjoy!
