A tempo deck with tons of evasion!

Pestilent Spirit has menace which will make early blocking tough, and when they can block Carnival will remove the blocker. That creates poor blocking choices for your opponent or removes them outright.

Deckhand is largely unblockable himself, but when combined with Yargle he creates a dangerous situation that demands an immediate answer.

For the other creatures we have 8 flying threats that will get through for easy damage. Then a couple sky tethers to make sure damage keeps getting through.

lastly we have the Forbidding Spirit that allows for us to attack recklessly against other aggro deck without fear of retaliation. Or at the very least limit the potential damage that can be dealt by the opponent allowing us to outpace them. Because our threats are unblockable their untapped creatures won't matter. They will sit there helplessly taking the pounding we give them.

As for defense we have Resolute Watchdog to keep something nasty through a board wipe and Dive down to help against intermittent removal. It also serves as an excellent early blocker for 1 mana! With the Gruesome Menagerie we can also get the Watchdog, Supreme Phantom, and a Pestilent Spirit to put us on a hard to break offensive right after a sweeper.

The reason for no hard removal is because the deck isn't trying to control the board. It is trying to manage threats and blockers long enough to kill the opponent. With all the 1 mana answers to various threats it allows for the deck to progress it's board state and answer the opponents cards without compromise.

The Anti Control Board is specifically designed to shut down control decks. It is something I am considering, because of how inherently strong the main board is against aggro decks.

The Sideboard is designed to provide additional stalling through Uncomfortable Chill and replace itself. Thief is a clutch play against green and controls decks for card advantage. Isolate is boarded in against Blue Tempo, green decks to stop turn 1 Llanowar, and is also strong against mono reds early Ghitu lava runners. Then finally make a stand is additional protection from board wipes and a little extra push to deal lethal to control.

This deck puts constant pressure on with multiple win conditions all in a simple streamlined fashion that requires no real setup. The tough situations just happen as a result of playing the deck without actually needing to actively pursue any combos.
