The way I have played him, I will use all of Ulix actions to grow pigs into warpigs. I always hire two piglets, and hire the sow to summon more piglets to grow. The aim is to end up with warpigs starting their activation within the majors aura, so that they can benefit from built in rams and positives to damage flips. All pigs must declare triggers, and they are not always very useful. Built in rams therefore allows pigs to heal in melee (which is always useful due to stampede and reckless) instead of facing the risk of ending up in a poor position (or ending their activation from «lie down and nap»(Gracie, sqealers and piglets)) due to triggers like rampage. When playing pigs, dont forget using the stampede ability, as multiple instances of pinging 1 damage will easily bring enemy models to low number of wounds, while pigs have multiple heal options (Ulix, slop haulers, tear of a bite).
