you can kill it. Instant speed removal will work best.
Discard also works.
Finally, you can just play with more 4 toughness creatures. It can't kill creatures too big for a single activation unless there are 2 in play (NEVER let there be 2 in play).
It sounds like your current build is one they can sit back and kill your creatures with Tower (because they're too small), and then save their counters for your few ways to remove it. Play with more things they have to answer and your artifact kill will go through. Play with bigger creatures and they can't just sit back on tower.
I use Dynavolt Tower. If they cast it on Turn 3 and tap out or only have one mana free then you are best casting something like Manglehorn. I've stopped using Towers because there is so much artifact hate in Amonkhet.
Nothing I do seems to stop it.
Thanks for the help.
Sorry if I'm moaning, but I can't deal with it. Hopefully ahmonket helps me deal with it or put it out if it's missery.

I have a 3rd in the side and 2 natural states in the side as well.
