Very cool customs Flameslayer! Would love to see the minis you had in mind for these, especially Elder Cloka. I really like the overall design of the Wrecking Crew; it feels very clean and classic. Although depending on the minis used I feel like they might be a better fit for Valkrill?
For the Cannon, I think it might be more thematic for it to have a static attack value, but a fixed range limit (maybe 4-7?) so that it actually couldn't be used to attack figures that were too close. I think what you have works well also, just wanted to throw out something for consideration.
I LOVE the idea of Temporal Warp as a power, and I think your implementation works well for the figure and point cost. I liked it so much, actually, you inspired me to design a different take on the power, maybe for use on another Chrono-mage at some point?
