Strategies
With
Portal Technician has below-average stats and no traits to help him fight whatsoever. While his ability can make decent, or even insanely powerful zombies like Wizard Gargantuar and Zombot 1000, the chances of him making an extremely weak zombie or a zombie that doesn't go well in your deck are equally high, making him a very unreliable card to use. The same applies if your opponent merely bounces him, as this will clear the lane without activating his ability.
Fortunately, Portal Technician can be a decent stalling zombie at the very least; since he makes a zombie on his place upon destruction, the lane he is on will be protected for at least two turns (or one if your opponent removes him via tricks). And his strength, while below-average, is good enough to pressure your opponent into not ignoring him.
If you wish to make him more offensively dangerous and treat his ability as insurance instead, using him in a science deck with Zombot Drone Engineer and Gadget Scientist would be a good choice, just note there are better science zombies avaliable for this purpose.
If you have Unlife of the Party, Portal Technician will boost Unlife of the Party twice: once for Portal Technician himself and once for the zombie he makes when he is destroyed. Some goes for Valkyrie; she will get +4 when both zombies are destroyed. However, only Professor Brainstorm can do this normally, and Portal Technician doesn't go well with decks that focus on these two zombies, as there's no reason to rely on such an expensive card when cheaper alternaives could take it from there.
Against
This zombie can be a tricky one to deal with since he will make a zombie on his place upon destruction, not to mention that there is a chance that said zombie can be a big threat. Generally, you should be ready for anything when facing Portal Technician, as you may either end up in a situation thinking you won, only for this zombie to make a game-changing one like Octo Zombie, Trickster, Zombot 1000, or scrambling to prepare for a tough threat only for it to spawn something useless. So far, the only ways to avoid his ability is to either bounce him and discourage the zombie hero from playing him again or transform him.
Outside of the danger level of the zombie made, Portal Technician can also block a lane for two turns thanks to that zombie. It is a good idea to destroy him before combat using damaging cards or bonus attacks, but try not to use an instant-kill card on this zombie as you may need it if a stronger zombie is made. Once he is destroyed, Portal Technician's blocking capabilities will only last for a turn once the zombie made is destroyed too. Play accordingly depending on what zombie is made.
