Wizard towers are good against loons. When placing wizard towers in a trophy base, you want your "wizard tower - air defense - wizard tower" ring to be equally balanced in a circle this makes the strongest anti loon feature in your base. Be careful with the size of this ring. If it is too big, the defense do not cover each other and it makes the whole thing pointless. If the ring is too small, your perimeter is not protected by your anti air ring at all and it makes a perfect base for loon+minion sniping.
For the antihog part, there is no rule to put it anywhere if you are a TH10. If you are a TH9 though. You want to put a wizard tower on either end of your double bomb bomb site. Two giant bombs going off deals 450 damage, a level 5 hog has 475 health, with a wizard tower securing one end of the bomb site, there is a chance that the hogs will be one shot even if a heal is preemptively put on your bomb site.
If you can mix both things up in your base then have a good position for your wizard tower.
