So, what sort of deck is worthy of a Swamp King
Aetherdrift - Start Your Engines // Max Speed Best card: Mendicant Core, GuidelightMendicant Core, Guidelight Runner-up: Samut, the Driving ForceSamut, the Driving Force "Start your engines" grants the player its first point of speed, which will increase by one during said player's turn if an opponent loses life, but it will do so only once
Enter Persist
its not like Jace, the Mind Sculptor isnt a little dubious of a package of repeated bounce and a fairly unassailable way to lock people out of the game, removing what hope they once had from their draw step
Estrid's InvocationEstrid's Invocation seems to be tailor made for this deck
To attack or use an ability, players must tap the card (turn it 90 degrees clockwise) to indicate its use (unless the card has vigilance )
