Dice Masters Fans! Teenage Mutant Ninja Turtles Dice Masters: Heroes in a Half-Shell is coming soon, and we’ve got some exciting previews of what the set includes!
First up is April: No Mere Damsel. Just like her shirt has the number 5 on it, April is essentially the 5th Turtle. The fact that she has Ally and Turtle Power means she’s a Sidekick and she’s going to help you pay less energy to access your Turtles. She’ll play well with the new Turtles or the versions from the first box set.
