This is a standard best of 3 mono red aggro deck.
strategy
The main strategy is all about using Burst Lightning, Shock, and Lightning Strike for versatile damage dealing, and Witchstalker Frenzy to deal with creatures that are too much for the other spells, or hitting your own Screaming Nemesis, transferring the damage to your opponent to shut off life-gain and/or close-out the game. creating growing threats such as Emberheart Challenger and Heartfire Hero whose abilities activate during combat from Manifold Mouse, Rockface Village, or from Monstrous Rage. In the event that Hired Claw is in your hand you can use him first since he grows bigger every turn, creating a huge threat until it is dealt with. This lets you hold off on playing other creatures, forcing your opponent to deal with it alone and letting you have other creatures in hand once they do. Monastery Swiftspear is a haste creature that grows temporarily from your spells, this one feels less significant but is a good card on its own. The late game threat is Screaming Nemesis. This creature has haste and can hit your opponent if blocked, shutting of their life-gain, or take out another creature.
sideboard
update
Added 2 Tersa Lightshatter to side-board
Removed 2 Obliterating Bolt from side-board
Remove 1 Shock from main-board
add 1 Monstrous Rage to main-board
This should solve my consistency problem. Monstrous Rage is way to important and I can phase out Shocks since Burst Lightning is a thing
Removed two Shock from main board and added Tersa Lightshatter. This increases the mana curve of the deck but allows for more versatility by cycling out lands or less useful cards.
Added 2 Soulstone Sanctuary to replace 2 Mountain in the mana base
Decided to go with only 2 tersa in mainboard. will side out if needed.
Added Magmatic Hellkite to side board to try out against decks with lots of nonbasics.
Added Wild Ride to side board to try out for triggering mice.
I ended up putting 2 more tersa in the sideboard for when I really want to use her draw ability
