I was never subject to any out of control Hellholt Engineers even though I was at two tables with two Martell players each, but is it time for FFG to add a "limit 3 times per phase" to all cards as a generic rule? Cards that need further restriction can still be 3 times per round. Are there any card effects that are appropriate to trigger more than 3 times per phase? To me it feels like if you can pull something off 4 or more times within a single phase you found something the card designers never considered.
