The goal of this deck is to be aggressive and put as much pressure on our opponents as we can.For that reason I'm keeping the CMC of the deck as low as possible.
Always Watching is a key piece in this deck, because by granting vigilance to all our creatures, we can exert them and still attack the next turn.
Of the exert creatures I consider Glory-Bound Initiate to be very important because against a deck like Ramunap Red it can provide us the life we need to stay out of killing range (with always watching out we have a 5/5 lifelink vigilance when exerting... potentially on turn 3!)
Ahn-Crop Crasher
is important because it can prevent the opponent from blocking.
Renegade Freighter
is a good 3-drop that I like to play because it kind of works like pseudo-haste on most creatures. Most creatures in the deck can't attack the turn they come down, but thanks to this vehicle it's still possible for them to push some damage through
Resolute Survivors
gives us some lifedrain, which can be the thing we need to push the last damage through or can put us out of the killing range of our opponents
Hazoret the Fervent She is brutal when she can come down and immidiately attack. With her ability she can get the last damage through even when our opponent stabilised the board. Occasionally I cast her without her being able to attack because she can still crew a vehicle.
Fleetwheel Cruiser works like copies 3 and 4 of Hazoret, while it's only guaranteed to be a creature for the turn it comes down, it will always be able to attack that turn, which is not always so for Hazoret.
Uncaged Fury and Invigorated Rampage are my favourite combo to kill an unsuspecting opponent out of nowhere.
