Buccaneers are a problem, but that's just because the board is too small. Make a bigger board, and just wait a bit for people to start using HtL3 or RB3 to stop early charges.
The issue with moo robe is I can't charge without getting my accuracy reduced, and if summoned first turn they get a leviathan's call which allows them to tank allot of hits and decimate my companions within a matter of rounds (also ruining their accuracy in the process)
