Zuckuss: Defender rerolls defence dice, multiple per round - 1 point
Elusiveness- rerolls 1 attack die effectively once per round - 2 points
R7 Agro- rerolls attack dice costing a TL once per round - 2 points
M9G8 - Attacker rerolls one die if TL'D (no cost to trigger), multiple per round - 3 points.
R4B11 - spend a TL to reroll all defense dice - 3 points.
Zuckuss feels pretty inexpensive to me in comparison.
The problem isn't that Zuckuss is 1 point though. In most situations, needing to take a stress token for every die that gets rerolled is enough to balance it. The average Degaroo build has so many discretionary points that having to pay 4 points for Zuckuss wouldn't really change much at all about what makes the list effective.
Zuckuss only really seems broken when the downside of using him can be almost ignored.
I'm not sure that Elusiveness would get taken much even if it was a 0 point EPT.
