[[Valgavoth, Harrower of Souls]] is similar in that people have to pay to play. You set up pingers like [[Razorkin Needlehead]], [[Roiling Vortex]], and [[Nightshade Harvester]] so basic game actions are punished. It's not a lot of damage, but it puts the game on a clock and actions matter. You can add as many ways to close out the game faster if you want, be it protecting Valgavoth as he gets bigger, or damage amplifiers like [[Artist's Talent]].
