+d3? The command ability grants one. You can stack it, so it's a bit more variable --
Per Frost Saber, you'd have [ 1 + Round Number + (Round Number)D3 ]+3 attacks. Or one less than that if you're going to give the re-roll 1s to hit.
So, turn two, you could easily have 2+2d3+3 attacks per cat, re-rolling ones. That's average of 9 attacks each, 4+ | 3+ | -1 | 1. If you could get 10 cats in, I'd think 90 of those attacks could insta-gib a hero or monster. (Estimated 40 wounding hits with -1 rend, 1 damage.)
But each cat gets 1+d3 (assuming you only use CP for the Hunter CA) each round you wait. And you're only sitting aside 320 points for this -- so yeah, I think there's something to play with there.
