over the terran with 20 ultras. Ultralisks are good against that specific combination if there is a low tank count, which is why terrans will still be making marauders for the follow-up tech switch, or just go mech where every unit except the hellion beats ultralisks per supply. Symbol also made good use of them in ZvP alongside infestors and banelings. Ultras crush FFs, fungal holds things still, banelings kill everything. Care to post those games? I've never seen ultralisks do well in high-level ZvP. The problem is that there are very few units which actually do lose to ultralisks per cost or per supply. Immortals crush them, as do colossi, chargelots, archons, etc. I think the only units that actually do lose to them are high templar (unmerged) and mass sentry. I could point to the jjakji vs puzzle GSL matches to say "the thor kills everything TvP!", but realistically most of the time the thor is going to lose to just about anything the toss throws at it.
