Innsmouth

Quick gameplay tips

That's not me messing up the format above, Innsmouth really do only have 1 minion in the deck - 10 copies of The Locals. They also specialise in cycling through your deck, specifically to retrieve more Locals.
Play Dagon as soon as you can. Once you're up and going it should be really easy to get out quickly, and it's your main way of scoring bases. Due to its tendency to be played on a base with lots of your power you don't really have to worry about it losing a clash of Titans - even if it does you should be able to replay it next turn if your opponents don't take care of the root Locals problem.
As Innsmouth you're all about inevitable strength. You may start slow but you gradually snowball your way to incredible power, your aim is to surprise opponents with how quickly you do it. Everyone knows what you do, it's not a game of outsmarting it's a game of SPEED! Beware playing against Teddy Bears and Princesses, who have crippling tools to prevent your gameplan (Bear Picnic and Eliza).

Gameplay

FATHER DAGON! I PLEDGE MY SOUL TO YOU ETERNALLY! SHOW ME THE SECRETS OF THE DEEP!

Innsmouth are all about ensuring unity among their minions, by any means necessary. One of us, one of us, one of us...They are the only faction in the game to have a deck made up of entirely the same minion - that being The Locals. By themselves, Locals are exceptionally good at gathering more Locals and not much good at anything else. Innsmouth's main strength comes from their actions - the overwhelming majority of which focus on playing extra minions and buffing low-power minions. The catch to these extra minion plays is that they must have the same name - something The Locals are more than capable of fulfilling. Once they've gathered up steam they're hard to stop, especially with their Titan in play - the mighty Dagon. Dagon provides a much-needed power spike for Innsmouth, giving them bonus power for all of their Locals and even allowing them to play more of them. Without Dagon in play they are substantially weaker, as they lack a good way to actually get all Locals to stick around. Their main ways of powering up their minions are temporary, which can leave them vulnerable to bloodthirsty opponents in the meantime. Their tendency to invest heavily on a single case can also mean that Innsmouth drop off in power quite heavily after a base scores, and skilled players will take advantage of this downtime to press their own offensive. Innsmouth have a few ways to combat this, Return to the Sea (above) being one such recovery card.
