Monastery Swiftspear is probably the best creature in our deck. You can play and attack with it in the same turn. If you really need a creature because your first one was killed, this is the best card to topdeck.
Kiln Fiend is a bit slower, but is still great for closing out the game, if you maybe didn't have a great draw. Getting +3/+0 for each spell is great for winning the game.
Blistercoil Weird isn't great, it's basically a 1/1 prowess for one, with the extra untap bonus. It is still strong though, because it only costs one mana.
Brute Force is a solid +3/+3 for 1 mana. The best pump spell in our deck.
Titan's Strength isn't quite as good, but it lets us scry 1, so it's a good upkeep play to set up your draw.
Mutagenic Growth will only be played for two life, but when it is played, you get +2/+2 for essentially nothing.
Apostle's Blessing keeps our creatures safe and unblockable. You play it for one mana, and it almost always lets you get your attacker through, while also giving it protection from some sort of removal spell.
Assault Strobe gives the biggest creature double strike, and it turns a 10/10 into leathal.
Temur Battle Rage does the same at one more mana, but is instant speed and also gives the creature trample, if they would otherwise just chump.
Desperate Ritual is a strictly better version of Pyretic Ritual, because of the splice effect. They both do essentially the same thing however, turning two mana into three, usually on the second turn of the game. They help us ramp up enough so that we can have that one extra crucial mana.
