On the other hand, the Wizard has the worst melee options in the game, and all of his in school big creatures are slow, so he needs way more position control to function properly.
I'll agree that Teleport is the most generally versatile, universally strong card in the game, but that doesn't mean that every Wizard necessarily needs 4. My Fire Wizard runs 4 Force Push and 3 Teleports (I really like Wall of Thorns in that build). I don't run Mage Wand in that build because the build is much too aggressive for wands. When I first put the build together, I included Elemental and Mage Wands, but after playing 4 games with it, I realized that I would never actually use those cards, so I pulled them out.
