Any +1's and comments would be great! I'm looking to make this deck be able to go toe to toe with other competitive decks so any suggestions on if I'm there/how to get there will be great.Sacrifice artifacts to pump up ravenous intruder and fling him to face. Pia's revolution to bring back artifacts or to burn down the opponent. Sideboard is full of board wipes, defense and other creatures in case the whole gremlin thing doesn't work against a particular deck.
Creatures:Foundry Inspector - These guy reduce the cost of all artifacts in the deck, which is 22 cards. Helps when low on mana and easier to combo off on a single turn.
Ornithopter - Some people might think that a 0/2 isn't great. You'll always be able to play it with it being 0 mana. Can block early 1 power guys and works well with the gremlins. Also, with Pia's revolution, it can 'theoretically' infinte, but they'll take the 3 damage, essentially it deals 3 damage.
Ravenous Intruder - The main man of the deck. Can sacrifice many of the artifacts we run to grow huge and attack, usually getting through with Key to the city. Don't be afraid to sac artifacts to keep the guy alive to dodge removel i.e lightning bolt.
Reckless Fireweaver - Drop this guy early and if it sticks around, can rack up 5-10 damage easy. Which it makes it easier to close games out if you can get the big gremlins through to attack.
Salivating Gremlins - The other gremlins in the deck. Not quite the powerhouse that Ravenous Intruder is as you can't choose when the buff happens, you'll have to hold cards in your hand if you want that to happen. It does however have trample though so damage could quite easily get through.
Scrap Trawler - With all the sacrifice in the deck, we need some recursion. This guy is excellent for that, artifact creature to sync with the rest of the deck. And brings back artifacts when it or another one dies. With artifacts at the 3 2 1 and 0 mana cost slot, a 3 mana artifact can chain react to getting another 3 artifacts back into your hand.
Workshop Assistant - Another little bit of recursion. Can get anything back you need, not bound to getting an artifact with lower cmc.
Gleaming Barrier - These guys replaced the Servo Schematics. When they die they make a treasure so a two for one for the gremlins or mana ramp if you want to use the treasure. They came to mainboard because they provide much more defense than the 1/1 servos.
Enchantment: Pia's Revolution - This is a bomb of an enchantment. Players either take 3 damage or let us get an artifact back when it hits the graveyard. With all the synergy with artifacts, getting the artifacts back is great for us. And with the amount of artifacts we have, they'll never be able to keep taking the 3 damage each time.
Artifacts: Fireforger's Puzzleknot - Just a cheap artifact, deals one damage when it comes into play, good for getting in a little bit of extra damage. You never really sac if for the damage, instead sac it to the gremlin.
Implement of Combustion - I believe these artifacts are called eggs? 1 mana and draw a card when it dies! Crazy! Once again, you never really sac it for the damage. The low cmc of these things back it the best artifact in the deck.
Key to the City - Great for getting the unblockable on one a buffed up gremlin. Kinda card draw as well, we don't mind ditching artifacts sometimes or extra lands.
Instant: Fling - A great card to include. Great if you can't get the damage through by attacking. Just be careful, if it get's countered you still have to sac the gremlin. Can come quite as a surprise.
Glorious End - Kinda a joke card, but pretty funny.
Sorcery: Hijack - Good if your opponent has one big creature you can't get passed, another card which can help get some big damage through. Removing a blocker and some extra damage from the creature you stole.
Sideboard coming soon.
